Researchers in MIT's Urban Planning and Studies department have developed tools to facilitate networked access to geospatial data. Their goal is to use smart servers to provide customized snippets of digital orthophotos using just-in-time geoprocessing and interoperable web-based components.
The MIT OrthoTools are freeware extensions to popular GIS packages that import customized snippets of digital orthophotos from any WMT (web mapping testbed) compliant server over the Web directly into the mapping window of your GIS package.
The extensions add two customized buttons to your mapping window. The first button allows you to specify a WMT server and choose a layer and image format. Whenever you want to slip an image under your map, click the second button and a fresh image, sized to fit the extent and resolution of your viewing window, will be extracted from the WMT Server.
These tools support the standard protocol developed under the OpenGIS Consortium's Web Mapping Testbed. They are based on previous tools which supported MITOrtho servers that used a similar protocol.
