Choice of Visible Layers

Simple Samples

Choose visible layers

This sample uses the TatukGIS Developer Kernel for ASP.NET to internet publish vector street map coverage's and a TatukGIS PixelStore format image layer. The data used for this sample is similar to that in the prior sample except that the image layer is a TatukGIS PixelStore file, as opposed to the "TIFF" image file used in the prior sample. The TatukGIS PixelStore format is an SQL based virtual tiled image hierarchy system that offers top speed with even the largest image files.

Refer to the TatukGIS web site for information on the advantages of the PixelStore format. The TatukGIS free Viewer may be used to create a PixelStore image file.

This sample demonstrates how to select which layer(s) are to be visible in the map presentation. Options are to present only the image layer or the SHP format vectors or both image and vectors together. It is important to name the layers in the project file and use the function LayerActive("layer") in the proper way with the names given to the layers.
