Download high resolution satellite imagery free online

free download satellite imagery free-thinkinfi


In my last few tutorials you have seen what LiDAR data is and how to do LiDAR data analysis.

High resolution satellite imagery is most important part while visualizing result after analysing LiDAR data.

In this tutorial I will show you how to download free high resolution satellite imagery.

Step1: Visit National Map Site

Visit USGS national map site (https://viewer.nationalmap.gov/basic/

Step2: Select Area of Interest

Search for any location or draw polygon or provide coordinates etc.


We are looking for imagery data covers LiDAR data. As this post is an extension of my last post to download LiDAR data, in this post also will use same coordinates.


Min Lat: 43.30099010129026
Min Lon: -88.85407447814943
Max Lat: 43.306661588070774
Max Lon: -88.84051322937013

Area of Interest to download satellite imagery

Then click on Draw AOI button.

Step3: Select Map Layer

Now need to select USGS Imagery Topo from layer (Top right of map) for better observation of map.

Step4: Select LiDAR data footprint

The satellite image you need to do LiDAR analysis. So before downloading satellite image you need to check the satellite image you wish to download is covering LiDAR data or not.

To do that you first need to mark footprint of your LiDAR data in the map.
Follow Step4, Step5 and Step6 to mark footprint of your selected LiDAR data to the map.

Step5: Select satellite imagery data type

After selecting footprint again click on Datasets tab from top left.


Now uncheck Elevation Source Data (3DEP) - Lidar, IfSAR and select Imagery - NAIP Plus (1 meter to 1 foot)

Step6: Search for LiDAR data Product

Now click on Find products

Step 7: Choosing best imagery for your LiDAR data

download NAIP satellite  imagery by coordinates

Now in Products tab list imagery products will be available. By clicking footprint of each product an AOI will be drawn in map. In my case only one imagery is available for my provided coordinates.

Step7: Download satellite imagery free

After selecting best satellite image data, click download button to download high resolution satellite image for LiDAR data analysis.

That’s all.

Note:
Most common formats of satellite imagery are:
  • JP2
  • TIF
  • TIFF

Our downloaded imagery data format is JP2.

Conclusion

In this post I have shown how to download high resolution satellite imagery free online. In my previous post I have discussed how to download LiDAR data free online and in my next post I will show you how to use these imagery and LiDAR data develop something interesting.

If you have any question or suggestion regarding this topic see you in comment section. I will try my best to answer.
