Enter Geospatial Data in the Data Entry Form

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 IMSMA^NG:

• Manual Data Entry
• Drawing on the Map
• Importing from Excel spreadsheet
• Importing as a shapefile

To enter the geospatial data into IMSMA^NG, click on icon 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 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.
