Natural Resources Database


NRDB Pro is a free gis tool for developing and distributing environmental databases. It was designed to provide people in developing countries with a powerful yet simple tool to assist in the managing of their own resources.


Data Dictionary

The Natural Resources Database is a spatial database. As well as storing data of type text or numbers you can also store point, polyline or polygon data.

The data structure of NRDB Pro is hierarchical. This means that, for example, you can represent the administrative structure for your project area and calculate statistics based on this.

NRDB Pro is also a time-series database, all data has a date associated with it. You can therefore observe changes over time in the data.

All data for the NRDB Pro is stored in a single database file which can be redistributed with the software.

The database structure consists of features and attributes. You define these in the Data Dictionary. You can define a structure that meets the needs of your project. NRDB Pro is therefore is applicable to a wide range of environmental / socio-economic projects in developing countries.


Safe Water Isumbo

Maps consist of layers. Each layer contains a spatial attribute, e.g. an administrative boundary or the location of a village, and a text or numeric attribute to be used as a label e.g. the name of the village, or the number of households above the poverty threshold.

You can create thematic maps whereby the way the layer is displayed is determined by the values. For example you can make the fill colour or symbol size dependent on the value or you can use different colours to indicate houses with and without access to safe water.

You can also change other aspects of the appearance such as the type of the symbol and the positioning of labels.

NRDB Pro includes automatic layout for printing of maps.

NRDB Pro supports UTM and other transverse mercator projections. UTM projections can be selected simply by clicking on the world map.


Query dialog

As well as simple selection of features and attributes to display on maps, graphs and reports you can also use queries. These give you more control over what is displayed. With queries you can apply conditions, e.g. only select data for 2002 or display only households that are not formal settlers and are living in makeshift housing.

Queries can also be used for calculating statistics. You can for example count the number of households below the poverty threshold by municipality. You could also normalise this by dividing it by the number of households in each municipality.

In the same way that you can add layers to maps, by selecting values or using queries, you can also produce reports.

You can also output data as histograms, time-series graphs and pie charts.

Digitising, Import and Export

Data can be encoded directly into the NRDB Pro software. You can also encode data into a spreadsheet and then import it into the NRDB Pro software.

Spatial data can be imported from shapefiles or text files. NRDB Pro also includes a utility for georeferencing image files scanned from paper maps. You can then digitise directly using the NRDB Pro software.

You can export map layers to shape files.

Seen to be a good GIS free application but is it possible to open a remote spatial database connection (in my case Oracle 10g)?

Sorry to post my question on your comment section, I just didn't found any other contact information on your website.

Hi Guillaume, thanks for question.

NRDB Pro only provides support for Microsoft Access (through ODBC) or MySQL databases. The latter may be networked. Polygons and polylines are held as large binary objects (BLOBs) so don't require a spatial database per se,

I can be contacted directly through my SourceForge account:
