Introduction

GIS links locational (spatial) and non-spatial attributes and enables persons to visualize patterns, relationships and trends – a new perspective to data analysis that cannot be seen in table or list format.

Integration of GIS into Planning:

Spatial data sources: Secondary sources,

Primary sources,

use of the data

Mapping with limits: Diverse sources of data,

Limited spatial data formats

Integration of Spatial Data in Planning

Secondary Data Sources

Shapefiles and Online services that

offer GIS files for download for

mapping general features (location

context maps, general forest cover

maps etc)

-----Not authoritative, accuracy?

o ArcGIS online,

o Bbike.com

Remote sensing (collection of

information from imaging

technology hovering/flying above

the area of interest) and Satellite

images (earth explorer, landsat)

------Not authoritative, accuracy?

Analogue maps and plans

(cadastral, topographic and thematic

maps) -----Digitizers (Manual) or

Scanners (Auto)

THE LIMITS!:Challenges while Integrating Spatial

Data to Planning

Spatial Reference: o Different datum/different coordinate systems

o Different Data Sources

o Missing spatial reference

Different scales and formats: o of topographical maps,

o of cadastral plans (RIMs, Survey Plans, PIDs)

Cost implications:o buying data (satellite images),

o scanning, printing, digitizing

Access of data:o permissions,

o justifications,

o bureaucracy

Recommendations

Adequate budgetary & resource allocation on spatial planning (Counties, National govt’ etc.)

National automation of all land records

Policies: Development of National Spatial Data Infrastructure (NSDI)

oPolitical good will,

olimited resources
