Digital Elevation Models : A Guidance Note on How Digital Elevation Models are Created and Used - Includes Key Definitions, Sample Terms of Reference, and How Best to Plan a DEM-Mission
Digital elevation models (DEMs) represents the elevation of the earth’s surface in the form of a digital image where each pixel contains an elevation value of the center point of the pixel. DEMs are a primary input to any modeling or process quanti...

description |
Digital elevation models (DEMs)
represents the elevation of the earth’s surface in the form
of a digital image where each pixel contains an elevation
value of the center point of the pixel. DEMs are a primary
input to any modeling or process quantification involving
the earth’s topography and are used across several areas of
development. Access to elevation, and slope maps enable
responders to assess where floods will infill the landscape,
create inaccessible areas, or create health risks, example,
cholera. DEMs are also used prominently in infrastructure
planning and mapping; road design and construction for
transportation; urban environmental planning to assess
construction, drainage, and green landscaping; agriculture
planting and irrigation strategies; ecological modeling to
assess ecosystem flora and fauna; and geological
applications such as seismic and coastal monitoring.
Accurate elevation information is therefore key for a wide
range of development projects related to poverty reduction,
urban development, water management, and other concerns.
Thus, the ability to design and commission or acquire DEMs
is increasing in relevance across the globe. This DEMs
guidance note aims to: (a) provide sufficient information to
understand the overall processes involved in the acquisition
of DEMs and their uses, and (b) inform and guide the
decision-making criteria; different design and
implementation strategies; and options and costs that exist
when acquiring DEMs. |
