GIS functionality plays a major role in spatial decision-making. GIS has the ability to perform numerous tasks utilizing both spatial and attribute data stored in it. It has the ability to integrate a variety of geospatial techniques like Global Navigation Satellite Systems (GNSS), Remote sensing and other conventional surveying techniques.
- Provides decision support.
- Increases efficiency and output
- Saves time and money
- Promotes data storage and sharing
- Supports data integration
Applications of GIS
- Land survey and Cartography
- Parcel identification, boundary demarcation and subdivision
- Map production (cadastral, topo and thematic)
- Urban planning
- Land use planning and control
- Road network mapping
- Utilities management
- Integration of data & information
- Supports better decision making
- Promotes greater collaborationamong public agencies.
- Improves accuracy & efficiency
- Environmental Management
- Pollution Monitoring
- Waste Disposal Management
- Management of water catchment areas
- Monitoring flooding
- Encroachment analysis
- Suitability analysis
- Precision farming
- Civil & construction Engineering
- Utility Management e.g. water & electricity

Creation of a Land Information System
The LIS consists of a cadastre that shows:-
i) Boundary information
ii) Owner details
iii) Location details
iv) Value of land parcels
v) Taxation and rates payment details
- Faster accessibility of land
- Information and data sharing
- Easy to update records
- Increases accuracy
- Reduces redundant datasets
- Improves data
Arch surveys has tried to apply modern GIS technics in assisting clients manage their prpopertis. In the resent times we have used GIS for the following tasks.
- 2006-2007: Perimeter survey for setting aside 1500 hectares in Yala swamp for the Dominion Group Satellite imagery and GIS was used to identify physical boundaries of the site as this is an area where ground survey was not economical. Client: Siaya County council.
- LIS has been used to manage several of the cooperative farms that we have been involved in. Currently we are working on a system for MAUWWA women group on their plots in Kisumu city. This involves 250 plots.
