Basic Steps for Working with Data

In order to gather or create data, and then add it to map layers, you need to
follow these basic steps.
1 Determine the coordinate precision and coordinate system to use. See
"Designing the Map" on page 112 for more information.
2 Create spatial data files and add them to layers. See the next section,
"Working with Spatial Data," and see "Specifying Data Source Properties
for Layers" on page 153 for more information.
3 Create attribute data and link it to spatial data. See "Working with
Attribute Data" on page 93 for more information.
4 Create raster images and add them to layers. See "Working with Raster
Images" on page 97.
5 Create symbols and add them to layers. See "Working with Symbols" on
page 104 for more information.
6 Create Zoom Goto categories. See "Zoom Goto Data" on page 96 for more
information.
7 Create reports and add them to the map. See "Working with Reports" on
page 142 for more information.
This chapter is designed to give you an understanding of the different types
of data you can use with Autodesk MapGuide, and how you create or procure
the data. For information about using the data in map layers, see Chapter 9,
"Working with Map Layers."

Working with Spatial Data

Coordinates that represent the geographic features on a map are called spatial
data. When you create a layer in a map, you specify which file contains the
spatial data to display on that layer.
Spatial data can be in a variety of formats. The native Autodesk MapGuide
format is SDF. However, Autodesk MapGuide can read spatial data from other
formats as well (such as Oracle 8i Spatial) if you have a data extension
installed for that specific format. For more information, see "Working with
Other Types of Spatial Data" on page 105. If you are creating a point or text
layer, you can specify an OLE DB data source, such as a table that contains
coordinates and text. For more information, see "Working with Attribute
Data" on page 93.
