TopoCAD is a basic yet comprehensive solution for surveying, CAD drawing, and engineering design; although he does more than that in an evolution that has taken him more than 15 years after his birth in Sweden. Now it is spread around the world, in 12 languages and 70 countries, although it does not seem to have achieved a high market segment.
TopoCAD is the star product of the company Chaos Systems, which also has RhinoCeros, a program for 3D modeling, robust but without much to talk about (this time). Also exists Chaos Desktop, a document manager, similar to what ProjectWise does. Although more practical, with integration to Microsoft Outlook and facilities to associate documents and metadata; for TopoCAD products it has a viewer, while formats like dgn, dxf and dwg can be viewed as images.
The concept of Chaos solution, through TopoCAD is very interesting, because its name falls short; Its applications range from data acquisition, correction and adjustment, CAD drawing, integration to GIS, engineering design and the cycle closes in the possibility of sending the data back to the surveying team.
Like any other, the line has a reader version, with the variant that a plus can be included to import and export to dwg / dxf formats or interact with surveying instruments. The rest is a modular range, they can be formed into packages between topography and design or they can be acquired independently to taste, according to the roles that are clearly established in the model:
From the field to the desktop: Topography / CAD. The package called TopoCAD Base includes COGO, it can connect to surveying equipment, it can make traverse adjustments using the least squares method. It can also operate terrain models (DTM and TIN), including what your results imply, such as contour lines, profiles, volume calculations, and cross sections (not the layout). As a CAD tool it has everything you could demand, with precise construction commands, being able to call reference or import common formats such as dwg, dxf, dgn, landXML and shape files. However as a top format, it can handle many attributes within the same map, similar to Xfm of Bentley Map. Also the Base module includes reader of layouts (sheets) and reader of attributes of database or metadatos of Chaos Desktop.
From the desktop to the Database: GIS / Maps. It happens that the top format is not a simple CAD with attributes, but its xml schema stores information that can then be sent to an ArcGIS mxd, converting the tables and attributes as they would be seen in TopoCAD. It can also interact with databases via ArcSDE.
You can export to common formats such as kml, Mapinfo or spatial database. Recently the FDO connector was launched that allows interaction with open standards data such as MySQL, PostGIS, Oracle, MS SQL Server Spatial, SQLite, ESRI ArcSDE, SDF (Autodesk MapGuide), ESRI SHP, ODBC, WFS, WMS, GDAL (Geospatial Data Abstraction Library) (Raster), OGR (Vector format: shp, gml, dgn, kml, mapinfo, etc.).
From Desktop to Plotter: Plans / Maps. It has a great ability to create layouts, called sheets, with tables of data extracted from the attributes. Vector objects, both lines and figures, dynamic elements, with which operations can be done from the layout, for example, the text sizes in the model can be adjusted from the layout without much turning. Supports sketch-type work, as if to release artistic taste on a final product.
From the desk to Design: Engineering. It includes capabilities for geometric road design, as Civil 3D or any competition would. It also has something for design of railway tracks, tunnels, pipes, canals and levees.
The way the data are handled, for example the cross-sections is more dynamic than the common, there is interaction with both the alignment in plant and with the profile generated.
From Design to Field: Topography / Stakeout. The data of a design can be exported to files that the total station or GPS can use to operate. It does not matter that the data was converted to UTM on import, then it can be exported as planar coordinates to avoid damage due to projection settings. And then this cycle can be repeated over and over again.
Overall, I find it an interesting tool. A CAD with mapping, design and interaction with the topography capabilities. The base price starts from about $ 1,500, depending on what is added.
