What is Geospatial Survey?

Geospatial Survey a.k.a. Survey is the technique of determining the terrestrial or three-dimensional positions of points and the distances and angles between them. The planning and execution of most forms of construction require Surveying. It is also used in mapping, transport, communications and the definition of legal boundaries for land ownership.

Our survey methods

• GPS / Tachymeter Survey : We provide conventional GPS/Tachymeter based survey. By this, we can provide ground level measurement with very precise gps locations
• Leica Captivate Survey: We offer modern surveying of buildings, roads, waters or any agricultural parcels with Leica software and Leica instruments.
• Mobile LiDAR Survey : we can provide point cloud with a very high-density points like few thousands points per square meter.
• Survey with Aircraft: We offer land survey with both Airplane and Drone. Survey outputs are Airborne LiDAR, Stereo Images, Oblique Images and ECW.

Our Survey Experiences

Greenledge have an extensive experience in different types of Surveying and have a good number of satisfied clients. We have surveyors with 20+ years of working experience who can offer accurate surveying.

Our Survey Services

Basisregistratie Adressen en Gebouwen (BAG) and Waarde van Onroerende Zaken (WOZ)

The Key Register of Addresses and Buildings (BAG) is part of the government system of key registers. Property Valuation Act (WOZ) regulates the valuation of all real estate in the Netherlands for the purposes of, among other things, taxation and the housing valuation system.
For both BAG and WOZ, the administration needs to measure the properties (specially buildings) of each house in the Netherlands. Greenledge is always there to help you with those survey and measurement related tasks.

Basisregistratie Grootschalige Topografie (BGT)

The Key Register Large-Scale Topography (BGT) is a detailed digital map of the Netherlands. In the BGT, objects such as buildings, roads, water, railway lines and greenery are uniquely recorded. Greenledge offers services of measuring and registering BGT data to the central registration system of the Netherlands (LV).

Orthophoto (Geo-Tiff and ECW), Stereo Image and Oblique Image

Orthophoto, ECW, Stereo Images and Oblique Images are widely used services to collect different features of an area with their geo-location. Greenledge provides surveying using Aircraft to collect photos and deliver in one or multiples of those formats.

LiDAR Point Cloud

Point clouds are widely used modern data collection method. With mobile LiDAR or Airborne LiDAR, this method can collect 3D location of all points on and above the surface. Those data can be used for different types of work including 3D city model, DTM/DSM creation, extracting 2D/3D features with geo-location etc. Greenledge can provide both Mobile and Airborne Point cloud as per client’s requirements.

Our Survey Methods

GPS / Tachymeter Survey

Greenledge provides conventional GPS/Tachymeter based survey. By this, we can provide ground level measurement with very precise gps locations.

Leica Captivate Survey

Leica Captivate is an industry revolutionizing software for a variety of measurement instruments, including Multi-Stations and Total Stations, that creates the most realistic 3D renderings with familiar apps and easy-to-use touch technology. We offer modern surveying of buildings, roads, waters or any agricultural parcels with Leica software and Leica instruments.

Mobile LiDAR Survey

We can scan an area with mobile surveying with a car. In this method, we can provide point cloud with a very high-density points like few thousands points per square meter. Note that, this method is applicable for those area where car can drive.

Survey with Aircraft

We can collect both point clouds and Stereo/Oblique images as per client’s requirements. We do the survey both with Airplane and Drone

Message From Chairman

Greenledge specializes in the domain of Enterprise/CAD Solutions including all related data work which makes us able to deliver turnKey information systems. As an example: we are delivering high quality certified software for Front governments almost fully running from our own cloudservers. Our mapping services including state of the art digitizing from Lidar point clouds and stereo images.

We have created a mix of Global domain and IT knowledge with Asian workforce in last 20 years. Initial R&D and task breakdown was done full Front side. But these days new technology is picked up from our backoffice where Front side only focusing on the main lines, communication and smooth running processes.

We focus on long term relation and do not over promise. Our strengths lie in our team of good trained and motivated staff. Great achievement is our back office is able to run their own recruitment and training. ‘Working together…’ has been our slogan and drive over 20 years and I am convinced that drive is the main contributor to our success.

Greenledge have deep experience in the development of Enterprise applications both to accomplish specific technical and business goals in the Enterprise context, and also to integrate enterprise data and documents into the Enterprise environment, or Enterprise into the larger corporate IT environment.

What Is Enterprise?
Enterprise is an acronym for geospatial information systems. It is a combination of hardware and geospatial software for capturing, storing and analyzing spatial data. Computer Images of maps combined with databases of that corresponding map give an information which could be used many different purposes. Almost all information tends to have a geographical information component in them meaning every information is tied to a place. So in a case of a disaster or any other emergency, the geographical information component has precedence over all other information.

Space companies with dreams of colonizing other planets have invested in Enterprise Application development projects, which could trickle down to other important uses for Enterprise applications on the ground level itself. While on the ground level, 3D Enterprise looks to be a promising addition to an already competent technology. New styles of visualization techniques of Enterprise have meant a wider audience for the technology. As for the future of Enterprise in general, since the first records of cartography at 7 BCE to until today. Enterprise has a long way and it does not show any signs of slowing down anytime soon.
