Technological news in Geo-engineering - June 2019

Kadaster and KU Leuven will collaborate in the development of INDE in Saint 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 has remained limited. In an effort to help the ...

Testing the accuracy of Google 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 grid points, it returns a surface with contour lines integrated with the ...

Contour lines from Google Earth - in 3 steps

This article explains how to generate contour lines from 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,…

Leica Geosystems introduces new entry-level construction layout tool

An integrated environment - The solution that Geo-Engineering requires

We have had to live a glorious moment at a point where different disciplines, processes, actors, trends and tools are converging for 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 city mapping

It is very likely that we will never see a true SmartCity, with its idealized vision. It is likely that there are more basic needs in our contexts than thinking about the Internet of Things. Including, that what the solutions manufacturers are doing no one has asked them. The truth is that the race to position itself in ...

TopView - Application for surveying and topographic stakeout

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 for learning for each system, and in which we have data incompatibility being often impossible to pass the ...

Draw coordinates in AutoCAD from an Excel CSV file

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

BIM Advances - Annual Conference Summary

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

Accurate purpose-dependent cadastre - trend, synergy, technique, or nonsense?

Back in 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 it originally adopts the cadastre for tax purposes, and how that need to gradually integrate data, actors and technologies is carried out by 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 profiles themselves, we will see in this section the generation of the digital terrain model from when to import the points, so that ...

The steps to generate a map using drones

The generation of a map using this technique can be 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 ...

This important event has as objective to publicize scientific and technical advances ...

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

Could doing a job with LiDAR be more accurate than with conventional surveying? If you reduce times, by what percentage? How much does it reduce costs? Times have definitely changed. I remember when Felipe, a surveyor who did the field work for me, came with a 25-page notebook 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 x, y, z coordinates. Case 1: List of Directions and Distances Suppose we have this table of data from the field: In the first columns we have the stations, ...

Being a surveyor is a lifelong experience.

Ken Allred's love of topography knows no bounds, and his enthusiasm, for a study that appears to newbies as a mathematical equation, is contagious. Retired St. Albert MLA doesn't think twice about pointing out the power surveyors have once they nail their simple milestones in ...
