Kadaster and KU Leuven will collaborate in the development of NSDI in St. Lucia Even after many efforts, within the public sector, the wider / wise use of geospatial information in daily governance, public policies and decision-making processes It has remained limited. In an effort to help ...

Testing the accuracy of Google's elevation data - Surprise!

Google Earth provides access to your elevation data with a free Google Elevation API key. Civil Site Design, takes advantage of this potential with its new Satellite to Surface functionality. This function allows you to select an area and the distance between the points of the grid, it returns a surface with curves of level integrated with the ...

Level curves from Google Earth - in 3 steps

This article explains how to generate contours based on the Google Earth digital model. For this we will use a plugin for AutoCAD. Step 1. Display the area where we want to obtain the Google Earth digital model. Step 2. Import the digital model. Using AutoCAD, having the Plex.Earth add-ins installed. At first,…

An integrated environment - The solution required by Geo-Engineering

We have had to live a glorious moment at a point where different disciplines, processes, actors, trends and tools are converging towards the end user. The requirement in the field of Geo-engineering today is to have solutions with which the final object can be made and not only the parts; just like ...

Leica Airborne CityMapper - interesting solution for the mapping of cities

It is very likely that we will never see a true SmartCity, with its idealized vision. It is probable that there are more basic needs in our contexts than to be thinking about the Internet of things. Even, what the solution manufacturers are doing, nobody has asked for them. The truth is that the race to position itself in ...

TopView - Application for surveying and surveying

Every day we see that our needs are changing and that for different reasons we are forced to acquire different PC Software, GPS, and Total Stations, each with a different program, with the need of learning for each system, and in which we have incompatibility of data being often impossible to pass the ...

Draw coordinates in AutoCAD from an Excel CSV file

I have gone to the field, and I have raised a total of 11 points of a property, as shown in the drawing. 7 of those points, are boundaries of the vacant lot, and four are the corners of the house erected. When downloading the data, I have converted them into a file separated by commas, known as ...

Progress of the BIM - Annual Conference Summary

The progress of the standardization of Building Information Modeling (BIM) has been the cross-cutting theme of the Annual Infrastructure Conference, held in October in Singapore. Even though my Twitter account was practically hijacked with the hashtag #YII2017 in those days, here is a summary. The trip This time I ...

Precision-dependent cadastre of the purpose - tendency, synergy, technique or nonsense?

There by 2009 I elaborated the systematization of the evolution of the Cadastre of a municipality, which in its natural logic suggested a progress between the reasons why the cadastre for primitive purposes adopts for tax purposes, and how that need to integrate data, actors and technologies is a contextual integration. For 2014 ...

Import points and generate a digital terrain model in a CAD file

Although what interests us at the end of an exercise like this is to generate cross sections along a line axis, calculate cut volumes, embankment, or the same profiles, we will see in this section the generation of the digital terrain model from the moment to import the points, so that ...

The steps to generate a map using drones

The generation of a map using this technique can become a big problem, one of those problems is so critical with the consequences of losing valuable months of useful work when you do not have previous experience in this task. The founders of Aerotas Mapping System speak to us in a POB article ...

The Illustrious Official College of Geomatics and Topography Engineering announces the XI International Congress of Geomatics and Earth Sciences, to be held in the Toledo Congress Palace (El Greco), from the 26 to the 30 of October of 2016. This important event aims to publicize the scientific and technical advances ...

Traditional topography vrs. LiDAR. Accuracy, time and costs.

Doing a job with LiDAR could be more accurate than with conventional topography? If it reduces times, in what percentage? How much does it reduce costs? Definitely times have changed. I remember when Felipe, a surveyor who did the fieldwork, came with a 25 notebook pages of cross sections to generate with ...

Draw a polygon in Microstation from Excel

Using this template, you can draw a polygonal in Microstation, from a list of bearings and distances in Excel, or a list of coordinates x, y, z. 1 case: List of Directions and Distances Suppose we have this table of data from the field: In the first columns you have the stations, ...

Being a surveyor is a lifelong experience.

Ken Allred's love for topography knows no limits, and his enthusiasm, for a study that in the eyes of novices appears as a mathematical equation, is contagious. The retired MLA of St. Albert does not think twice about pointing out the power that topographers have once they nail down their simple landmarks in ...

MDT, A complete solution for Surveying and Engineering projects

With more than 15,000 users in 50 countries and available in Spanish, English, French and Portuguese among other languages, MDT is one of the Spanish-speaking origin applications most appreciated by companies engaged in geoengineering. APLITOP has four families of applications in its portfolio: topographic projects, field applications with total station ...
