8.2.11 Projections & Conversions
Level of expertise required for this Chapter: Intermediate; specifically for LUPMIS @ TCPD
These Tools cover all conversions between different reference systems (mainly, projections). Currently supported are UTM 30, UTM 31, latitude/longitude, GTM (with informal definition), War Office (approximate) and UTM in general.
a) Unit Conversion
Coordinate points can be converted between the projections, also batch routines of many points. Also, conversion of other units, such as length, area, degrees can be converted.
Just type the number or coordinates in the box, and press the Convert button next to it:
A training video shows the conversion of one point from UTM 31 to UTM 30 and its display in the GIS (in YouTube).
- b) Vector Map Conversion
- c) Raster Map Conversion
You can convert raster images (satellite images, aerial photographs, scanned topo maps etc) between different projections. Supported projections are currently UTM 30, UTM 31, latitude/longitude, all UTM zones, GTM (currently with inofficial definition), War Office (approximate).
With the option 'Many maps' you will convert all raster images of the selected type (e.g. JPG). For this, you select the folder and any file in this folder, as show below. It will then pick this file and all others of the same type.
- d) Projection identification
