    • Content Development! 2 Development! 3 The TOP file contains more 4 "We wouldn't manage without Topocad" As you grow older and actually can start to look back in time, 6 Machine control and machine guidance you see that there has been a lot of development during the 7 International training course 7 Point clouds and scanning years. This year will be my 20th year in the business. The 8 Get to know Topocad and its modules first survey I made was the first GPS measured digital terrain 10 The Topocad history model in Sweden ever. It was back in 1990, on a fairly flat 11 News in Topocad 12 surface around a parking lot and a lawn, outside a convention 12 Tips & Trix, Contact information centre in Gothenburg. Back then, we downloaded the data and calculated a DTM from this survey. Fantastic. p.4 A couple of weeks ago I held a training course for a group of surveyors and mappers, and when we introduced ourselves, one of the surveyors said: “I began my first employment at this office, in December 1965. Back then we didn’t have that much theodolites”. I guess not. It’s only 45 years ago but still, it is a lifetime of work. Since 1990 the speed of development has been high, of course, and sometimes you think that, now, this is it, we cannot go further, it is good enough! During the last 20 years p.8 the GPS has really burst into bloom. Today, I have 1 GPS with map in my car, two others in my boats and I actually have 2 GPS receivers with maps in my pockets at the time of writing. Built in my two mobile phones. And if the satellites go down I can make a rather good interpretation of my position from the mobile phone connections anyway. I remember when the robotic total stations came, it was first named “robotic” station. I made a lot of work towards a Geodimeter 468DR back in 1992-1993. The one-man station came and concurred, at least up here in the Nordic where you cannot find anything else than the one-man stations today. After that we had to wait a while for the next big innovation step. Some connections between GPS and total stations were made but it took some time to get them up and running. However, as I see it, the next big thing was the scanning and LIDAR. You haven’t bought one yet? Well, you will. Most probably.

    • The TOP file contains more As you notice, the TOP file becomes bigger than Typical GIS DWG and DGN when you save it on your hard A typical GIS file, as Shape files, contains X, Y and disk. Why is that? Well, it contains more. possibly Z, information about the type of object and layer names (divided in separate files) and a lot It contains more data than ordinary CAD drawings, of attribute data. Not much more, no colours, no it contains a lot more data than coordinate files and blocks, no line types. So it is three words of data it actually contains more data than GIS files like that is quite far away from each other. Shape or Mapinfo files. So what does the TOP file contain? So what do different format contain? To start TOP - as the coordinate file - contains X, Y, with, all files we discuss here contains X and Z, Point Id, Point Code. TOP - as the drawing Y-coordinates. But that is the only thing they have file - contain layers, colours, line types, blocks in common! A coordinate file, typically used by (symbols), texts, line widths, arcs, circles, the surveyor, contains what is important for the polylines, polygons, splines, dimensions, etc. As surveyor. X, Y and also Z (height) coordinates. the GIS file it contains all kinds of attribute data Point number and Point code. It might also have connected to any type of object, not only blocks. some special code and perhaps some attribute data. It does not end here, the TOP file also contains individual settings for each attribute shown in the What about drawing files? drawing/map and it also contains imported road Drawing files contain quite much. Except for lines with spirals. X, Y and Z coordinates they also contain layer The TOP file is an intelligent hybrid between all information, colour, line type, block and geometry these different types of data sources and you will as line, curve and circle.

Topocad is In my department we would not manage without one of his most important tools. Topocad. For example, we use the programme to convert the DWG files we receive from constructors SVEAB is a full service company that handles and architects. We convert data, that usually was commissions of great variety.

Do you have any favorite functions? - A function I appreciate a lot is the option to add or remove parts of a polygon. For us, this facilitates the handling of areas and dotted land considerably. The polygon handles both holes – polygons within the polygon – and islands – polygons outside the polygon. Polygons are supported when importing/ exporting through, among others, ISM and ArcGIS connectors. - I also frequently use the function to build up a terrain model in 3D, insert height on the lines and also study the terrain models in 3D. With the help of different colour levels and 3D I notice immediately if something is incorrect or if a point has ended up in the wrong place. Do you have any tips for new Topocad users? - It is fairly easy to get started in Topocad. I worked with the programme for about two years before I took SVEAB is building a passage for pedestrians and cyclists under the railroad at the Central station in TOPOCAD Uppsala. magaZine SPRING 2010 Page 4 http://topographi.blogspot.com/

We will make our own internal format .TPC (Topocad Point Cloud), an indexed file with functions This will give all of our users a simple way to handle for import of other scanning file formats as LAS files. huge amounts of point cloud data to create traditional The TPC file will be possible to use instead of or in cross sections, profiles, volume calculations and combination with DTM files: contours! 1. Terrain cross section creation, use a TPC file instead of or in combination with one or several DTM files. The cross sections will be created from the DTM’s where they exist and from the TPC file in other cases. Of course it will be possible to use both for terrain sections only as well as designed cross sections using a section template. 2. Terrain profile, when you need a terrain profile (terrain longitudinal vertical section) you select to create this from the TPC file instead of a DTM. 3. When you create a DTM from a PTS file, you will be able to select parts of the PTS file to create a DTM from this to use it as a DTM in all other commands. 4. Volume calculation by model, calculates volumes between a flat surface to a PTS file or from a DTM file towards a PTC file. 5. Create contours directly from a PTC file. In Topocad 12.2 item number 1, 2, 3 and 4 from the list above will be available. Item number 5, Create contours, is scheduled to a later release. With Topocad point clouds we take an important step towards meeting the modern way of achieving data. We see that the demand from our users is high to find a way TOPOCAD magaZine SPRING 2010 Page 7 http://topographi.blogspot.com/
    • Get to know Topocad and all its modules What is Topocad? Topocad is a CAD system developed for surveying calculations, COGO, transformation and for mapping, design and GIS connectivity. A system made for surveyors and designers Topocad is a true object orientated CAD system especially made for survey, calculation, mapping and design. Topocad has been developed by an experienced team of engineers which resulted that the development of Topocad started from a surveyor's point of view. Whether you are a civil engineer or a landscape architect, a surveyor, a tunnel designer or a database manager, Topocad has the right application for your job. The Topocad modules are "add-on" packages that increase the field of applications. Topocad is a user friendly and easy to learn CAD tool. You don't have to work with it every day to be in control. Being on the market for several years, Topocad has reached many thousands of users in more than 100 countries and is translated into more than 17 languages. The Topocad maintenance agreement keeps you up to date with the latest developments. Base module Profile The Topocad Base module contains a complete CAD, The Topocad Profile contains profile form, interpretation and communication towards total stations, levellers, GPS editing of profile, heights on road lines and surface check. The instrument. It also provides the user with dimensioning, module is not only used for creating professional profile forms transformation, code table, terrain modeling, contour lines, road lining, export/import to a number of file formats, LandXML and a built-in 3D viewer Topocad reader & reader PLUS Topocad reader is a TOP viewer and can communicate towards an instrument and calculation of survey data. Also, import of files and export of some file formats is possible. Topocad reader PLUS is Topocad reaser plus possibility to import and export DWG/DXF. Topocad engineer Topocad engineer is a smaller version of the base module, and but also for creation of the profiles from surveys, from profile contains foundation CAD, the most of Topocad´s CAD engine, form and terrain profiles, it handles camber and cross falls communication towards instrument, calculation of survey data and really everything that has something to do with vertical and import/export of files. heights on long-stretched objects as road lines, railways, pipes, TOPOCAD magaZine SPRING 2010 Page 8 http://topographi.blogspot.com/

    • The Topocad history In late 1993 Chaos systems was founded, we got a CAD with number 05 was actually the fifth module and why the management contract for the huge infrastructure project the base module is number 08 – well think of that… Northern link in Stockholm. This gave us the possibility to start the company and already from the beginning we had an In 2001 the Survey module had been that much, with all CAD, idea to develop a CAD software with integrated functions for communication, terrain model, road geometry – and then there survey calculation, communication and with integrated digital was a need for less functionality for a much smaller price. So terrain model as well as road geometry calculation. we had to make a module of the base module (08) and licenses without module became the Topocad Reader. Then Topocad In May 1994 the first code string was written for Topocad. Not junior or in Mapsuite+ words the Mapsuite+ Foundation. even 8 months later, in January 12, 1995, we shipped the first At the same time we cut the functions of Volume sections in 92 licenses already sold at that time, without anyone seeing it two – terrain sections and theoretic sections – so the terrain for real yet. Topocad 1.0 was not that much compared to today, sections (only) was made module number 09. The modules 10, but anyway, it was a new thing then. It was 32bit Windows, it 11, 12 and 13 was smaller add-on’s with point database, map was a true CAD and it was made for surveying and mapping. sheet reader. The TOP format was already then bigger in that way that it contains more data than other formats in this line of business. In 2004 we made our first database connection together with This thing with 32bit wasn’t that easy at the time. Windows the Swedish company Spatial technology with connection 95 didn’t come before end of 1995 so we had to use the 16bit to their ISM (Independent Spatial Management) adapter to operation system Windows 3.11 with a feature called win32s.

This gave us a lot of knowledge into this world and a Not so compliant, not so steady, so it gave us a lot of headache couple of years after that we got a question from the Swedish until Windows 95 came. Windows NT worked fine though. Land Survey to make an adapter to ArcSDE from ESRI. Said and done. It was ready 2006 and with this we got really into Since then, Topocad has been steadily developed and we have the mapping and GIS world and we have hundreds of users put many many thousands of hours behind the development. working with this adapter every day. The latest database And we have got thousands and thousands of users of Topocad adapter we developed was the Open Source adapter FDO since then. Almost every year one version has been released.
