Note.jpg You have to specify the Coordinate System and Coordinate Format you would like to use before starting to enter the geospatial data.

There are several options to enter geospatial data into IMSMANG:

To enter the geospatial data into IMSMANG, click on Pencil for points.pngicon in the Data Entry Form Editor window.

The interface to enter geospatial data manually or by drawing on the map consists of two tables: a Points table, and a Polygon and Polyline Points table.


Point and Polygon/Polyline List Window


Buttons for Entering Geospatial Data
Button Description
Preview Geospatial Data Allows you to preview the geospatial data on the map.
Import Points Allows you to import geospatial data from an Excel or shape file.
Draw on Map Allows you to record the geospatial data by drawing on the map.
Add Allows you to manually enter geospatial data.
Modify Allows you to manually change the selected point.
Delete Allows you to remove the selected point.


After you have entered the polygon/polyline points, IMSMANG displays the total calculated area size and line length of the polygons and/or polylines.

Point types

Which point type that should be used depends on:

  1. if is it a single point;
  2. if is it a point that is part of a polygon / polyline;
  3. the type of contamination.

Point types used for recording of areas are of two main types;

  • single points;
  • part of the polygon.

More information on which point type to be is found here.
