Download Aerial Imagery
Download $40 of aerial imagery FREE using included DeLorme Data Dollars and the software's NetLink tab. Imagery can be used with all of the Street Atlas USA routing, GPS, and draw tools.
Authentic DeLorme Maps
Not licensed from 3rd party companies, the updated maps and 4 million places of interest are produced by experienced mapmakers at DeLorme.
Core Functions
Map Controls
The maps can be controlled using a variety of methods, including the traditional push-button zooming, which drills in/out while keeping the map exactly centered. Also, holding down the left mouse button enables you to drag and zoom, left-to-right, across the map, and moving the mouse in the same manner but in the opposite direction zooms out.
Find
DeLorme employs several powerful search capabilities within the software. The first is a simple box called QuickSearch where you type common requests including towns, cities, lat/lons, ZIP codes, street addresses, colleges, and many more to receive the quickest possible matches. The places-of-interest search offers more advanced parameters and the advanced search is used when locating exact matches requires additional customer input.
Draw
Add MapNotes; draw your own circles, polygons, and squares; measure the area of your draw objects--even draw in your own roads and route on them--these are amazingly powerful draw tools for the money.
Info
Right-click on the map to learn more about what's underneath your cursor. Lat/Lon, names of streets and bodies of water--even local radio station information--can be viewed in this manner. Moreover, the bottom toolbar of the software displays a continuously updated readout of what's underneath your cursor.
Voice
Use your voice for issuing routing and GPS commands while tracking. Ask common questions such as "How far to my next turn?" and the software answers. Microphone recommended for optimal usage. The software also reads upcoming turn information, including the time to turn, time to finish, and name of the street to turn onto. New voice settings allow you to select how far in advance of your turn you'd like to be prompted. Voice can also be turned off if you prefer.
Netlink and Aerial Imagery
NetLink is your online link to DeLorme for $40 of free aerial imagery now included with the Street Atlas USA 2010 versions. Select your areas of interest and download only those grids to the software. Toggle the imagery on and off in a single-screen view. Add notes and draw objects to the imagery to customize lifelike views from space.
Mobile Device Mapping
Pocket PC, Windows Mobile 5.0 and later, and Palm OS Compatible
Included at no extra charge is the DeLorme Handheld software, which now includes support for Windows Mobile 5.0 and later devices. Access the maps you want from the desktop software and hot-sync to your PDA. Add a DeLorme Bluetooth GPS for use with Bluetooth PDAs and navigate wire-free.
The DeLorme handheld functionality provides address-to-address routing, spoken directions, mobile map colors to reduce in-vehicle glare, and four million places of interest. Finding what you need is easy using the powerful search capabilities. Now you have powerful desktop mapping software and PDA software all conveniently provided in one Street Atlas USA 2010 package.
Maps on iPods
Using a tool similar to how MapShare works, now you can select the maps you want from the desktop software and send them to your photo-capable iPod. These map images are static (e.g., cannot be manipulated once on the iPod) and come across in the order you select them, same as with photos. Once on your device, you can access the ones you need, when you need them. Due to the small screen size of iPods, we recommend these maps for urban walking situations where you can discretely reference the maps you need. (Not GPS compatible.)
Convenience and Security on the Road.
Imagery can be used with all of the Street Atlas USA routing, GPS, and draw tools.
Ease of Use
E-Z Nav Wizard
New E-Z Nav wizard makes on-the-go searching and routing a breeze. Just search on any category (see below), choose your destination (retailer, hospital, gas station, friend's address, etc), and start real-time navigation with your GPS receiver on your dashboard. Great for daily and overall trip planning, too.
NavMode
NavMode brings together all the primary GPS controls and readouts needed when using the GPS. Large-screen views make it easy to see the map and directions. You can switch between 2-D (standard) map view and 3-D perspective view for lifelike views.
Keyboard Shortcuts
Set your own keyboard shortcut preferences for optimum control when using GPS. The key-bindings function is very powerful and advanced so you can design your ideal in-vehicle navigation solution to your personal specifications.
Map & Travel Information
Map Data
Because all DeLorme map data is created, updated annually, and owned by DeLorme, we are able to provide many features typically reserved for expensive in-vehicle navigation systems. Free from the license restrictions and third-party dependencies of other publishers, we can also evaluate customer-submitted revisions and implement these changes after triple-checking all submissions.
DeLorme currently has an enhanced commitment with staff in place to make as many customer revisions as possible.
Places of Interest (POI) Data
The DeLorme database contains over 4 million annually updated places of interest across the U.S., with additional ones in Canada, including restaurants, lodgings, gas stations, travel services, RV stops, truck stops, malls, shopping - just about everything you could ever need on the road. The software settings let you choose the magnification level to display the various POIs to void cluttering your map views. The POIs can be accessed using the many Find capabilities or by right-clicking on the map and selecting places based on type and distance from map center.
GPS Features
GPS Radar Search
Now you can travel with GPS and have the software find upcoming travel services based on their location from you. Find gas, hotels, shopping, and much more in your direction of travel and then easily make detours to these desired stops along the way.
It's like having your personal travel concierge with you at all times.
Automatic Back-on-Track GPS
Using the Earthmate GPS LT-40, which turns a laptop PC into a powerful GPS navigator, it's possible to have the software offer new spoken and visual directions when you stray off course. Within the GPS tab of the Options section of the E-Z Nav toolbar, you can select or type the off-route distances you want to travel before the automatic recalculations kick in. Select short distances for city travel and longer ones for highway travel where you may exit frequently for roadside travel services.
GPS Spoken Directions
The software can offer voice directions indicating upcoming turns and street names. It also can be set up to respond to your voice and answer common travel questions--a very powerful capability for mapping software within this price category. Several different voice types are included.
Printing & Sharing
Print
Print crisp color or black & white maps that you control to best match what is seen on screen. Also print Travel Packages containing strip maps and directions to bring on your trip. Don't want to use a lot of ink and paper? Then print just the Turn Details which show thumbnail maps of each of the decision points along your route.
MapShare
MapShare makes it easy to share your customized maps and directions with family, friends, and business associates. You create exactly the Map you want and then post within our online MapShare library, which includes private administrative tools for you to manage. Similar to some of the better online photo resources, MapShare allows you to provide controlled access to your important maps without worrying about email and spam filters.

Hydraulic Design of Highway Culverts, Second Edition
Author: Jerome M. Norman, Robert J. Houghtalen, and William J. Johnston | Size: 8,6 MB | Format:PDF | Publisher: National Highway Institute | Year: 2001 | pages: 368 | ISBN: none
Hydraulic Design series No. 5 combines culvert design information previously contained in Hydraulic Engineering Circulars (HEC) No. 5, No. 10, and No. 13 with hydrologic, storage routing, and special culvert design information. The result is a comprehensive culvert design publication. Hydrologic analysis methods are described, and references cited. Culvert design methods are presented for both conventional culverts and culverts with inlet improvements. Storage routing techniques are included which permit the designer to account for ponding effects upstream of the culvert. Unique culvert applications, erosion and sediment control, debris control, structural aspects, and long-span culverts are discussed and references cited. Inlet control, outlet control, and critical depth design charts, many of which are newly developed, are included for a variety of culverts sizes, shapes, and materials. New dimensionless culvert design charts are provided for the design of culverts lacking conventional design nomographs and charts. The appendices of the publication contain the equations and methodology used to construct the design charts, information of the hydraulic resistance of culverts, and methods of optimizing culvert design using performance curves and inlet depression. Calculation forms are provided for most of the design methodologies in the manual.
The second edition corrected minor errors and provided both SI and English (U.S. customary) units for all equations and design charts.

This European Standard deals with the requirements and the basic performance criteria and specifies minimum
values where appropriate for precast hollow core slabs made of prestressed or reinforced normal weight concrete
according to EN 1992-1-1:2004.
This European Standard covers terminology, performance criteria, tolerances, relevant physical properties, special
test methods, and special aspects of transport and erection.
Hollow core elements are used in floors, roofs, walls and similar applications. In this European Standard the
material properties and other requirements for floors and roofs are dealt with; for special use in walls and other
applications, see the relevant product standards for possible additional requirements.
The elements have lateral edges provided with a longitudinal profile in order to make a shear key for transfer of
vertical shear through joints between contiguous elements. For diaphragm action the joints have to function as
horizontal shear joints.
The elements are manufactured in factories by extrusion, slipforming or mouldcasting.
The application of the standard is limited for prestressed elements to a maximum depth of 450 mm and a maximum
width of 1 200 mm. For reinforced elements the maximum depth is limited to 300 mm and the maximum width
without transverse reinforcement to 1 200 mm and with transverse reinforcement to 2 400 mm.
The elements may be used in composite action with an in situ structural topping cast on site.
The applications considered are floors and roofs of buildings, including areas for vehicles in the category F and G
of EN 1991-2 which are not subjected to fatigue loading. For building in seismic zones additional provisions are
given in EN 1998-1.
This European Standard does not deal with complementary matters. E.g. the slabs should not be used in roofs
without additional protection against water penetration

BS 7448-3:2005 Fracture mechanics toughness tests. Method for determination of fracture toughness of metallic materials at rates of increase in stress intensity factor greater than 3.0 MPa m0.5 s-1
This part of BS 7448 describes a method for determining the opening mode plane strain fracture toughness
KIc, the critical crack tip opening displacement (CTOD) fracture toughness and the critical J fracture
toughness of metallic materials. The method uses fatigue precracked specimens tested in displacement
control at rates of increase in stress intensity factor greater than 3.0 MPa·m0.5sp1 but less than
3 000 MPa·m0.5sp11) during the initial elastic deformation. Stress intensity factors greater than
3 000 MPa·m0.5sp1 are covered in Annex A. These rates are greater than those permitted in BS 7448-1.
The definition of fracture toughness values relevant to particular structural integrity assessments is
outside the scope of this British Standard.
NOTE This standard does not cover integrity assessments. Such assessments are covered in BS 7910.

BS 7448-4:1997 Fracture mechanics toughness tests. Method for determination of fracture resistance curves and initiation values for stable crack extension in metallic materials
This Part of BS 7448 gives a method for determining the resistance to stable crack extension of metallic
materials. The method uses fatigue precracked specimens. These are tested in displacement controlled
loading at a constant rate of increase in stress intensity factor within the range 0.5 MPa·m0.5s–1
to 3.0 MPa·m0.5s–1 1) during the initial elastic deformation. Resistance to crack extension is characterized
in terms of the variation in crack tip opening displacement (CTOD) and/or J with stable crack extension.
These characterizations are referred to in this standard as and J R-curves, respectively.
The method is only suitable for tests on specimens that exhibit stable crack extension. If unstable fracture
or crack arrest occurs in any of the tests in an R-curve determination it is necessary also to assess the test
results in accordance with BS 7448-1.
Testing requirements and analysis procedures are given which enable crack extension resistance curves to
be calculated from both straight notch and stepped notch compact specimens and single edge notch bend
specimens. Individual fracture parameters are also defined for CTOD and J at a point where stable crack
extension is close to the onset of initiation.
The definition of fracture toughness values relevant to particular structural integrity assessments is
outside the scope of this British Standard.
NOTE Publications of relevance to the subject matter covered by this Part of BS 7448 are listed in the bibliography in Annex A.
A system of crack plane identification is given in Annex B.
