# Heights and base maps of two industrial plots before construction

Base mapping. Location: Velimeşe OSB, Tekirdağ, Turkey. Year: 2023.

An aluminium manufacturer in the Velimeşe industrial zone (Tekirdağ) was about to build on two plots. Our partner MapSurvey surveyed the heights and produced the topographic base maps for both; the 3D model can be viewed on this page.

## What the project needed

Before designing a hall you need to know the ground: levels, slopes, boundaries and what already exists around it. The brief covered two plots with the same aim, and the product was the usual one for an industrial engineering office: spot height plan and base map.

The MapSurvey record of this job is brief, so this page keeps to what it states and explains the method in general terms.

## How this kind of job is approached

On open industrial plots, drone photogrammetry with ground control points is the usual method: the surface model gives the heights, the orthophoto serves as the background for drawing the map, and everything sits in the coordinate system the works will later be set out in.

## What was delivered

The products stated in the record, for each of the two plots.

- **Spot height surveys**: Ground levels for grading, foundations and drainage.
- **Topographic base maps**: Plan of each plot and its surroundings for the design and permits.
- **3D model**: Visual review of the plots and their surroundings.

## If you have a similar project in Spain

Ask for heights and mapping in ETRS89 and your UTM zone, as layered DWG or DXF with the height datum stated, and the orthophoto as GeoTIFF or ECW. To quote, we need the plot perimeters as KMZ, the intended use and whether vegetation or buildings hide the ground.

## A project by our technical partner

This work was carried out by MapSurvey, our technical partner in Turkey, measuring since 2015. In Spain, SensorFlight handles the fieldwork and the client relationship, and MapSurvey processes the data and delivers the models. Samet Bayram Gulyol, GIS expert at MapSurvey, is SensorFlight's technical lead.
