IMF Editing Tools

|

IMF Editing Tools is an extension that works with the Internet Mapping
Framework to allow the editing of spatial features and associated
attributes over the Internet.

The IMF Editing Tools Extension is a set of tools that can be configured
to work with specific layers in an ArcIMS image map service to interactively
modify the shape and attributes of a feature.
Separate tool sets are available for editing polygons, lines and points. Using
the tools provided, a user can edit or create shapes using on-screen digitizing,
COGO routines, and vertex editing. Vertex snapping and copying existing features
from other layers is supported.
Once a feature is edited, it can be saved using the save button. When this is
done, the feature attributes and coordinates are sent in a GML string to a
handler script. Geography Markup Language is a standard encoding for the transport
and storage of geographic information, defined by the OpenGIS Consortium. The
handler script is responsible for processing the request by inserting, updating, or
deleting records of the spatial data source. The process is extremely flexible,
allowing routines to update spatial data in SDE layers, shapefiles, or tables
in databases.
Example handlers have been developed using Java and JSP to update data in SDE
databases. The example handlers use ESRI's Java API for SDE, but it is important to
note that handlers can be developed using other technologies such as ActiveX COM
objects, C++ CGI programs, etc. This is similar to the way that reporting is
handled in the IMF.
