Survey Drawing Simplified

Historically, Civil Engineers were among the first users of Information Technology to increase productivity, back in the 60s and 70s some of the first computer programs written were FORTRAN programs for Civil Engineering calculations, including structural design, geometry calculations, and CPM applications for project management.

However, in the present day it is not as developed and far reaching as some of the other fields. The survey engineering field has also seen a similar growth in the past few decades. There are a few software products being developed for these fields in the recent years. Among them is a well established firm, ESurveying Softech India Pvt. Ltd., who develop survey related software available at affordable prices and user friendly interfaces. Their product packages include a varied range of applications including section generation, interpolation, contouring, earthwork calculation, KML, etc. and backs it up with equally quick and reliable customer support.

The ESurveying products are split into four main packages including 7 modules, which can be bought individually or as a complete package. This helps you to choose only the required features from the range of products, which allows you to spend less time in learning as well as makes the software cost effective.

Using the Sections module, Sections related to Road/Railway Lines/Irrigation Canal can be created either from Excel data or from CAD drawing. Section Module allows the user to modify the sections graphically. Available Section data can be interpolated along any alignment. Data can even be imported from Field book. Interpolation can be done using either triangulation or 3D lines. Output can be generated quickly as Designing both Horizontal Alignment and Vertical Alignment is simplified.

The Contour module allows you to generate contours at specified intervals and specified levels. The software also generates grid levels along with the contour generation and can be done from within CAD Software. This software includes attractive modules like Area and volume report depending on Contour area.

Using the Earthwork module, earthwork calculation can be done very quickly. It allows finding the volume of cutting/filling for a given set of data at a given elevation or it can find the earthwork quantities for any two surfaces.

The TopoDraw module allows you to create Topomaps using Easting, Northing and Elevation data available in Excel or CSV File. Using TopoDraw module converting total station data into drawing with blocks is made very easy.

The ESurvey Lisp module is a very useful tool for all CAD users as it provides a collection of tailor made lisp routines developed exclusively for CAD users working on Survey drawings. These lisps are divided into 18 different categories and allow you to get more control over the drawing entities and make your drawings more presentable.

The KML module allows you to publish your CAD drawing to Google Earth. Converting data available in Google earth in the form of KML File to 2 Dimensional drawing data and Vice Versa is made possible with ESurvey KML.

These products work with different CAD packages including AutoCAD, ZWCAD, BricsCAD and GStarCAD and allow you to work with only a selected set of required commands without learning thousands of commands provided by CAD packages. These products also work independent of CAD software for those who are not familiar with any kind of CAD packages.
