There are several reasons why land surveyors are increasingly adding drones to their portfolio of instruments. Firstly, using a can vastly reduce the time spent collecting accurate data.
Phoenix LiDAR Systems is the global leader in commercial UAV LiDAR solutions and specializes in custom, survey-grade mapping & post-processing solutions enabling clients to collect detailed, 3D topographic information for a wide-range of commercial and research applications, including engineering, construction, mining and more. Nowadays LIDAR data is widely used in different field. But the problem is, it is expensive and there are only few websites that provide access to download the data for free. Free LIDAR data are mostly from the United States area.
By acquiring raster data from the sky – in the form of geo-referenced digital aerial images, with resolutions as sharp as 1.5 cm (0.6 in) per pixel – you can gather millions of data points in one short flight. More time still can be saved by using a survey-grade drone such as the eBee RTK. Such GNSS/RTK receiver systems are effectively flying rovers, capable of receiving data corrections streamed from a base station or via VRS to achieve absolute X, Y, Z accuracy of down to 3 cm (1.2 in) – without needing Ground Control Points.
With collection made so simple, you can focus your energy on using and analysing data, rather than working out how to gather it. With such a large increase in the amount of physical data being collected, this does mean an increase in office time spent processing and utilising this data. However this expansion is cancelled out many times over by the huge time savings a drone produces out in the field.
Many of senseFly’s surveying customers say, for example, that large jobs that once took weeks can now be completed in just a few days, and that a week’s worth of traditional data collection is now achieved in just one day. Last but not least, less time spent on the ground means staff safety is improved by minimising risk to surveying teams when measuring sites such as mines, unstable slopes and transport routes. Simply choose take-off and landing locations that are out of harm’s way. Anyone involved in mining knows that worker safety is of paramount importance. By allowing surveyors to collect accurate spatial data from above, or UAV technology can vastly reduce risk by minimising the time these staff spend on site. Drone-based data collection can also boost productivity; surveying projects that once took days or weeks using traditional surveying techniques are now possible in just a few hours.
Plus, thanks to a drone’s ability to collect data from above, there is no downtime required while surveyors move around a pit, as can be the case when using terrestrial surveying instruments. With fewer man hours required to produce large, accurate data sets, and no need for externally-sourced imagery, the result is vastly reduced costs. In fact, many operators report that a single imaging drone – comparable in price to a mid-range GPS rover – can pay for itself in just a few months. Topographic base maps for large scale projects of many 1000's ha size is now possible to + / - 25cm in days not months or years. Topographic surveys for large scale projects such as plantation, mining exploration, oil & gas concessions, route studies, geothermal power projects, power lines, pipelines, roads and more can now be made available within days or few weeks at project start up. LIDAR is an airborne laser scanning technique which when flown together with DGPS can provide data to generate terrain models to +/- 250 mm accuracy. LIDAR can be flown, processed & contoured maps made available to client literally within days or few weeks instead of months or years by conventional means such as air photography or ground surveys.
Often at project start up accuracies better than +/- 25 cm are not required and LIDAR can provide rapid mapping with an accuracy resolution that is more than “fit for purpose” at an early stage of any project start-up. Tomorrow's technology today! Clients can now have terrain models and contoured topographic mapping for large scale projects which can be combined with high resolution satellite imagery or air photography to produce base mapping in the form of combined topographic and other thematic maps (geology, surface water, vegetation, soils, etc.) at scales that are useable for planning, feasibility, preliminary and even detailed design. These can be combined with published maps from “desk top studies” to provide project start up base maps that in the past were unavailable or took many months or years to produce. For better results combine LIDAR with satellite mapping or air photography taken at same time.
Geoindo provide airborne LIDAR, satellite imagery & air photography services through their strategic association partner INFOTERRA – a European Space Agency company. One of the most experienced operators and processors of LIDAR in the world. Two Optech airborne laserscanners (lidar), ALTM-1020 & ALTM-2033 model, are available. Both of these instruments are capable of recording a very dense grid of height points on the ground surface beneath the aircraft at a rate of 5,000 and 33,000 individual height points per second respectively, allowing millions of height measurements to be captured in only a few hours of flying. The ALTM-2033 can acquire a grid of height points, spaced at approximately 1 metre on the ground with a vertical height accuracy of better than +/- 25 cm.

At the same time the ALTM-2033 also acquires a panchromatic image, which aids interpretation of the height information and image classification. The ALTM-2033 instrument is also capable of acquiring both first pulse and last pulse returns, which makes the instrument suitable for acquiring a Digital Terrain Model (DMT) and Digital Elevation Model (DEM), even through dense vegetation cover. Both instruments have been used for a wide range of projects including seismic planning, facilities planning and route corridor analysis for pipeline routing. To date we have undertaken surveys in ten countries in terrains ranging from desert to tropical rainforest.
Operations flown worldwide and in the UK.

Has made our. So why not have them at #1 in a list specializing in LiDAR data sources? If you don’t know about Open Topography, you should probably take a peek. The beauty behind Open Topography is its open community system. When users register, they can upload their data so that the larger community can access it.
You too can help grow Open Topography into one of the biggest open data portals for free LiDAR data. Open Topography is a collaborative data repository for LiDAR users. Intuitive web map displays LiDAR points as downloadable data with metadata. Previously, USGS LiDAR data could be accessed through CLICK (Center for LiDAR Information Coordination and Knowledge).
However, this service is now being provided by the. So you want USGS Earth Explorer LiDAR data? If you’re new to this platform, we have a. For LiDAR, it’s a simple process: First, enter your search criteria (kml, coordinates, etc.). Next, select the checkbox for LiDAR in the data sets tab. Finally, click the results tab to see what LiDAR datasets are available.
Search for LiDAR data with a user-friendly state-of-the-art interface. Filter searches by time and set region of interests in map by predefine areas and coordinates Also, USGS Earth Explorer sits on top of our, so it’s definitely worth your time to know it inside out.
3 United States Interagency Elevation Inventory There’s been a movement in the United States for a National LiDAR Dataset. This innitiative is being led by the United States Interagency Elevation Inventory (USIEI). Also, it’s in collaboration with NOAA and USGS. Several states have moved forward in their own collections.
To see exactly which states they are, the gives you this information along with vertical accuracy, point spacing, and date of collection. Downloading the physical data is not so straight-forward. The maintains download source locations.
LiDAR sources are decentralized with partial and incomplete data across the United States. USIEI LiDAR data viewer displays the nationwide listing of known high-accuracy topographic data. 5 LIDAR Online Who knows?
This may be where the future of LiDAR is going – a global LiDAR map. We have the Earth mapped with optical imagery already.
LiDAR Online’s mission is ambitious. No matter where you live, this data source shows you exactly where on Earth is LiDAR. Admittedly, a little bare now in terms of LiDAR sources, shows a lot of promise.
LiDAR spans the globe – mostly Europe, North and South America and Africa. Webmap with points delineating free LiDAR data sources. 6 National Ecological Observatory Network – NEON One of the cool things about the is that they are funded by the National Science Foundation. Another neat thing about NEON is the amazing work they are doing with airborne LiDAR to map out vegetation stands. Although some of NEON’s data may not have sufficient QA/QC to meet the end-user’s needs, we still think NEON’s airborne LiDAR data has some serious potential.
Minimal selection of LiDAR because in construction phase. Beginning of a collection of publicly available LiDAR. Because the file sizes are so large for LiDAR, they are typically stored in LAS or its compressed version LAZ.
When you process LiDAR data, you can convert to ASCII, GeoTIF and several other formatfs. There are open source options available to convert LiDAR files.
For example, ArcMap can do it. But, there are open source options too. My personal favorite free open source LiDAR conversion software is Whitebox Geospatial Analysis Toolbox GAT. Many people don’t know about it but its very powerful.
We’ll make a tutorial on converting LAS files in the near future. Thanks for your question! Site behaves strangely. If you check the info of most of datasets they are said to be free but the download button is not there. After two days of unsuccessfully searching for download button and watching the tutorial of how to use the site (the download was happily available on the video) I decided to go to FAQs. There, it was said that 5€ was the minimum payment to be able to download or use LiDAR data online. OK, I decided to pay but on the payment page the minimum charge turned out to be 10€.
This doesn’t seem like a serious aproach and makes me think that once I pay 10, on the later stages the conditions might change again. Decided not to deal with them.
