An alphanumeric string used by Autodesk MapGuide Server to determine
whether a map layer has permission to gain access to a resource. In the Autodesk
MapGuide Server Admin, you can assign one or more access keys to a resource. Then,
when a map author sets up a layer to use that resource, the author must type one of the
valid access keys in the Map Layer Properties dialog box.
ADL

Autodesk Data Link file.
arbitrary
XY
coordinates
Cartesian coordinates that specify points on a particular
map, which do not correlate to coordinates on the globe as latitude/longitude do. An
arbitrary
XY
coordinate system is suitable for floor plans or very small sites.
ArcView Shape file (SHP)
A data format that includes files created in ESRI ArcView.
You can convert these files to latitude/longitude SDFs using the SDF Loader.
attribute data
Alphanumeric data that describes the characteristics of map features.
Attribute data is maintained in tables and databases, which are linked to map layers in
Autodesk MapGuide Author. Examples of attribute data include street names, building
addresses, land-use codes, and population counts. Attribute data is used either to label
map features, create themes, or generate reports. See also
spatial data

attribute table

database
and

Autodesk Data Link file (ADL)
A file that establishes a connection between Autodesk
MapGuide Server and Autodesk DWG files. ADL files are similar to UDL files but have
an
.adl
file extension. You can create or modify ADL files using Autodesk MapGuide
Server Admin.
Band Interleaved Line (BIL)
A format for compressing raster images that consists of
an unstructured file and an ASCII metadata HDR file that are combined into one file.
BIL

Band Interleaved Line
.
bmp
A format for compressing raster images that is typically used for icons or images
that need to load quickly.
BNA file format
A data format that includes files created in ESRI Atlas GIS. You can
convert these files to latitude/longitude SDFs using the SDF Loader.
bookmark
A saved view position and zoom magnification identified by a URL that
you specify. When you use a bookmark, the map is redrawn at the view position and
zoom magnification saved in the bookmark.
buffer
A polygon that locates its boundaries at a certain distance from a point, line, or
other polygon. An example of a buffer is a polygon whose boundaries are 200 feet from
the bank of a river.
