Surveys are used to capture land's topography, this has numerous applications.
Topography is the mapping of the earth's 3D surface. It's a way of documenting the landform of an area, including hills, valleys, rivers, and planes.
The data is represented visually by contour lines, therefore, allowing the 3D landform to be understood in a 2D format. Each contour line represents a specific elevation above sea level.
Municipal council applications (building permission or re-zoning)
Architectural, infrastructure, and landscape planning.
Creation of a 2D Basemap or 3d model (low or high-resolution topographic data)
High-level water retention strategies and earthworks.
There are various ways to get topography data, detailed below. However, the first question is always: WHY is the topographic data needed? In essence, how much precision is required for your specific context?
There is public data (topography) available for the entire world, however, for many regions, the data is low-resolution and therefore may not be too useful. However, Sometimes low-resolution data can provide value regardless, so it all depends on your context and intentions.
Some regions of the world have high-resolution data available online, in which case, we may be able to retrieve your land's topographic data remotely.
If high-resolution topography data is required, yet not publically available, performing a survey is the solution.
