Laikipia (Kenya) Research Programme GIS Datasets
Entry ID: NBId0177_101

[ Update this Record ]

Summary
Abstract: Laikipia Research Programme GIS Datasets are divided into two main
different study area scales: the Regional level [Laikipia district,
the Ewaso Ng'iro Basin] and the Local level [Land parcels-farm(s),
catchments of a few kilometer square].

Coordinate Reference System

Coverage data is organized thematically as a series of layers. The
coordinate reference systems used in LRP dataset are:- (a) global
coordinate system - Universal Transverse Mercator (UTM), (b) Local
coordinate system.

Digitizing Scale and Fuzzy Tolerance

The initial digitizing scale for the LRP GIS Dataset is dependent on
the scale of the study areas. There are two major research levels
carried by LRP namely Regional and Local. The scales used for regional
level are 1:250,000 and 1:50,000.

FUZZY TOLERANCE is the minimum distance between coordinates in a
coverage. The resolution of a coverage is defined by the minimum
distance separating the coordinates used to store coverage
features. Resolution is limited by the map scale in initial
digitizing. The fuzzy tolerance can be calculated as follows for
digitizing table:

Initial Scale for Coverage of Fuzzy Tolerance
Digitizing Units Value
1;250,000 Meters 6.35
1:50,000 Meters 1.25
1:10,000 Meters 0.25
1:5,000 Meters 0.125
1:2,500 Meters 0.0625
