The future of geospatial mapping is here thanks to advanced photogrammetry techniques that yield unbelievably accurate 3D models of land, buildings, and even small objects. These 3D renderings, images, and point clouds can be used for everything from land surveying and engineering to 3D printing, and new applications are being discovered every day. Our mapping services include:
- Geo-referenced orthomosaic images
- Orthorectified images
- Topographic surveys
- Contour lines
- 3D surface and structure models
- DEMs, DTMs, and DSMs
With assistance from land surveyors, these models and images are accurate to within centimeters, and without the assistance of land surveyors, are still highly accurate for most purposes. All of the models can be imported into CAD software like AutoCAD, and we can even compute volumes for materials and other stockpiles from the data. The images can be imported into Google Earth or other mapping software for up-to-date or interval imagery on new construction or land that is not within the high-resolution range of popular mapping applications like Google Maps.
What does all of this mean in English? It means we can take photos of your home, business, or land, and use the data for precise planning or mapping, and we can do it for a fraction of what it costs for other methods, with more detail and accuracy.
Let’s take a common example… Let’s say we have this small building and we need to make plans for expansion. All we get from Google is an image like this one, with very little resolution to start with.
We need a lot more data if we’re going to design something around this such as additional parking, or ADA ramps, etc. So that’s where we come in. We would come and take images from various angles and compute anew and better image that looks something like this.
Now we have an orthorectified aerial image that is already much better to work with. But actually… it’s not. This is actually a point cloud with real data in every single pixel of this image. It’s scaled and placed in real-world coordinates and we can take measurements directly off of this map to create a site layout. But wait, there’s more! We can also take a look at the building from an oblique perspective, and from this view, we can also measure the height of objects and learn about the ground elevations, finished floor elevations, ramp slopes, etc.
For any point on this image, we can extract coordinates X, Y, and Z. We can take measurements in any direction. We can even see and measure the utility poles, parking spaces, and even mechanical elements on the roof! The detail is incredible.
