Yes and they're free. Nearly all map layers presented within our Map Maker are available for use outside the National Atlas. You can download these map layers at no cost using file transfer protocol (FTP). See our Raw Data Download page for more information about downloading National Atlas map layers. The following private company sells National Atlas raw data on CD-ROM. See similar questions...

The field of GIS requires many different skills in a variety of areas. To find out what these are check out my article on “Building a Career in GIS” See similar questions...

In traditional knee replacement, an approximately 10 to 12 inch skin incision is made centered over the knee. This is followed by making an incision into the quadriceps tendon above the knee, down the side of the kneecap and two inches below the joint and then the kneecap is flipped 180 degrees and off to the side (everted). The knee is then bent up to expose the bones of the knee for resurfacing with the knee prosthesis. See similar questions...

The difference is in the size of the skin incision and, more importantly, how much muscle and tissue is cut to put the total joint components in. Cutting less muscle results in less pain, less swelling and potentially a quicker recovery. No, the same components are used in MIS hip replacement surgery that are used in traditional surgery. They are just put in through smaller incisions in the skin and muscle using specialized instruments. See similar questions...

The SDO uses fluid silicone to guide the foot into its best position on the ground naturally. A traditional orthotic confines the foot to a pre-set position and tries to control the foot through the footstep. The SDO is the only orthotic in the world that moves with the motion of the arch and cushions the end of the motion where the foot gets ready to move off. A traditional support stops the motion abruptly, which makes it impossible for most people to tolerate beyond the first 2-4 months. See similar questions...

This is hard to answer because I don't know what "traditional modeling" within your environment. In many organizations the traditional approach to modeling is to develop relatively detailed models before coding begins. Sometimes these models are kept up to date, sometimes they are not, and sometimes they're even used to generate code (often a good thing). Each of these models are often created by a single, expert person who typically spends most of their time working alone. See similar questions...

The map data is output in a shape file format. The majority of GIS software will utilize this data format. Please refer to your specific GIS software for specifics on importing. See similar questions...

this time, we are not offering a search function on the site. To acquire more information on a parcel, use the zoom/pan tools. Once you find the parcel, use the "identify" tool to select it. When the parcel is selected the report tab will show on the left with more data about that parcel. See similar questions...

Yes. We are currently searching for the proper GIS map application to apply on the TrafficInfo site. Until then, we will try to improve the navigation of the maps with the next release of the site. The information contained in the next release will be displayed using ASP.NET. This technology, however, requires the procurement of newer equipment. As we wait for this new equipment to arrive, we will continue the development of the next version on our test servers. See similar questions...

Search by Keyword - search for "Texas", "Arrowsmith", "Geographical", etc. The search is case insensitive. View a much larger page that shows "all maps" or some other large category. As these pages are slow, the previous searches are preferable. See similar questions...
