The document discusses the application of remote sensing and GIS in mapping for land resource management, detailing techniques such as planimetry, digital elevation models (DEMs), and thematic mapping. It emphasizes the importance of accurate mapping for industries such as forestry, mining, and utilities, particularly in developing countries aiming to enhance their geographic knowledge. Additionally, it outlines the requirements for high-resolution imagery and the various uses of detailed mapping products.

- 5. :MAPPING: • Mapping constitutes an integral component of the process of managing land resources, and mapped information is the common product of analysis of remotely sensed data. • Mapping application of remote sensing include the following: 1) Planimetry 2) Digital elevation models (DEMs) 3) Baseline thematic mapping (BTM)/Topographic mapping
- 6. • Mapping product including the resource companies like forestry, mining and oil; support and service industries (engineering); Utility and infrastructure development agencies ( pipelines, telecommunication, transportation, and power), government mapping agencies and military. • Developing countries are currently intiating mapping programs to cover large unsurveyed areas to increase thair topographical and planimetric knowledge base. :MAPPING:
- 7. • Planimetry consists of plan measurements, including angles, distances, and areas. • It is in 2D dimension (X-Y plan). • It’s generally required large-scale application like urban mapping, facility management and general landscape information. • Very high resolution imagery is usually required for accurate planimetric mapping. • Scope of planimetric application-Transportation route information, building and facilities location, general land cover. :Planimetry:

- 9. • A digital elevation model (DEM) is a 3D CG representation of a terrain's surface – commonly of a planet (e.g. Earth), moon, or asteroid – created from a terrain's elevation data. • It is in 3D dimension. • It is crucial for performing geometric and redio metric corrections for terrain an remotely sensed imagery. • Elevation data are used in production of popular topographical maps. • DEMs associated with Resource management, telecommunication planning, and military mapping. :Digital Elevation Models:
