Before you can do a project, you need to know the size of the land where it will be situated. You need to know the gradient and slope of its faces – you need to be able to calculate how much material you need to remove and how much you need to bring in. You also need to know where the features of the structure should be located and what needs to be done to reach those positions. That is why we prepare topographic maps.
The purpose of topographic mapping is to collect information on the features within a location and to organize it into a map drawn to an appropriate scale. Topographic mapping requires the use of surveying techniques for data collection. Data can also be collected using remote sensing techniques including satelite imagery, aerial and drone photography as well as compilation from secondary sources such as other maps. Once all the data has been collected, the next phase is cartography – which is the art and science of map making. Modern maps are developed using GIS technologies.
Once the map has been prepared, it needs to be produced in the appropriate format. If the map is intended to be printed, a plotter is used to print the map. The map may also be shared in soft copy as a PDF or uploaded on a web GIS platform (such as our own MobGiS). Please visit our shop to order our services online.
Have you heard the horrendous story of the developer who started construction on a project that was larger than his property? Smart developers prepare a detailed map of the site before development. A smart architect will insist on a surveyors report. Why risk losing so much by not doing your due diligence?
We usually develop topographic maps by gathering data regarding boundary information as well as the existing conditions such as existing roads, buildings, powerlines. Topographic mapping also provides information on heights which is useful for planning drainage and other structures. We use GIS software for preparing our maps, which can be provided to the client in any format of their choice.
