Topographical Surveys

The level of Topographical survey varies depending on the client's specification. This can range from a basic boundary & level survey to fully detailed topographical surveys which includes all significant visible above ground features. Each feature surveyed is assigned a unique feature code, which enables the software to distinguish and differentiate between the data surveyed. The principle we follow is to carry out thorough accurate coding on site, to minimize later editing required in the office .The policy of True Earth Surveys Pvt. Ltd for project surveyors to process their own data; and not for it to be passed to a CAD department to be edited by someone who has never seen the site! The work carried out by our CAD department is general drawing layout and presentation, once the project surveyor has completed his/her edits. We feel this is the most accurate way to produce a survey drawing.

We understand the importance of a comprehensive survey drawing, and if required can include significant features adjacent to the site being surveyed; e.g. overlooking window positions, ridge & eaves heights etc.. This additional information can be included on the plan drawings, and also supplemented by annotated digital photographs. With the "non-contact" Direct Reflex "DR" survey equipment that we use, We are able to survey these features remotely, without gaining direct access.

Rather than surveying the site in isolation, this additional surrounding information gives a more complete picture of the site situation. We can provide the survey data as 2D contoured plans, and also as 3D computer digital terrain models (DTMs). With the inclusion of proposed design information from the client, volumes of site material can be calculated, and also rendered site visualization exercises can be carried out.

Survey drawings can be provided as traditional plans plotted on paper or film, and also on disk in a variety of software formats, including:
• AutoCAD DWG & DXF
• Civil 3D
• AUTO PLOTTER
• KMZ
The various software packages that we have in-house have a variety of export options, so we should be able to accommodate your requirements. We understand the importance of being able to open a drawing and start working with it immediately. We keep a record of clients' requirements, which is kept updated. This can include survey specification, CAD file layering structure etc., and other special requirements. Our aim is to provide you with a quality drawing in the correct format that you can work with straightaway.
