Opening Map and Layer

Add Layer

GIS map is the display of overlaying many different typed layers, consisting of many different layers. It supports two types of layer: Feature Layer and Raster Layer. SuperPad 10 supports GEO layer, which is the Supergeo self-developed vector data format. A GEO layer has two files. One is the GEO file (*.geo), used to record the spatial data containing feature information and spatial information; the other is DBF file (*.dbf), used to record the attribute data, in which every record of attribute corresponds to a property of the feature in GEO file. Vector layer includes three types of layer as point layer, line layer and polygon layer.

Besides feature layers, SuperPad supports many different imagery files in raster layer. Overlaying feature layers and raster layers enables users to compare data, highlighting the theme of files. The supported raster files include ECW(*.ecw), MrSID(*. Sid), JPG (*.jpg), GeoTIFF (*.tiff), JPEG 2000(*.jpeg) and SuperGIS Raster SGR (*.sgr) Supergeo self-defined. The world files always accompany raster layers to describe the datum information for the image. Moreover, raster layer can only be displayed in SuperPad, but cannot be edited.
