Viewshed example

GIS At Work: Viewshed Analysis

MN DNR Lands and Minerals team was asked a very good question: Would there be concerns about a new communications tower near the Boundary Waters? How might this impact potential recreational users? Would the the safety lighting be visible from pristine natural wilderness? How could we model visibility under existing and varying conditions?

Hello Viewshed Analysis!  Viewshed analysis utilizes a set of GIS functions to examine cross-sections of the landscape, so specific points can be observed at any distance and trajectory from an ‘observer point’.

We are fortunate to have LiDAR data that includes canopy intercept (first return) as well as terrestrial surface readings. A canopy normalized digital surface model (nDSM) was used and the visibility tool was run for differing tower heights and offsets to account for the observed canopy. LiDAR also allows bare earth measures to demonstrate ‘perfect’ visibility, with no ground cover. This would model a clearance event such as logging, wildfire, or blowdown. With GIS, the analysis was run multiple times to produce a variety of viewable probabilities.

For the visibility question, the GIS viewshed analysis was able to provide data-driven confidence in likely impacts for a range of alternatives. Although the GIS was impressive and very useful, in the end a table helped communicate which height may have the least (or most) visible impact. Decision makers relied on the data to tell the story and the discussion moved forward.

Layer Transparency example

GIS Tip: Transparency

Setting the transparency property for a layer in GIS is a very helpful  when you need to keep a polygon fill color but still want to see the base layers drawn under your layer. This is also helpful when trying to draw a raster layer above vector layers (like shown in picture!)

HOW? In ArcMap: Double click on the layer in the table of contents and go to the layer's display property to change the transparent setting, click OK to apply. In ArcGIS Pro: Select the layer in the contents pane, then go to the Appearance tab's Effects group, change the transparency value and click enter to apply.

Layer Properties

Do you have a GIS Tip? We'd love to hear from you! Share your tips or ideas with the DNR GIS Community Team. It's a great place to share and learn! Next time you do something fun or cool in ArcGIS feel free to share with us all; we're all virtual GIS cube mates in the DNR GIS Community Team!

Jim Olson

Get to know Jim Olson

What’s your role:  I’m a web liaison and all-around GIS analyst for DNR Lands and Minerals.  I enjoy outreach to other staff, helping them with new spatial analysis, and providing GIS tips and tricks to people at our LAM GIS User Group.

What aspects of GIS work do you enjoy most:  I like to help people find their way through a problem, analyzing data and seeing what stories the data reveals.  It’s satisfying to go from question to answer and to help people on their own terms.

What’s a project that’s had a positive impact:  I’ve been working on our Drill Core Library project which is all about looking at this data set that has been around for a long time and seeing how we can make it more accessible to staff.  For example we’ve been able to tie it to a mobile Survey123 project and use it to help inventory where in our facility various drill-core materials are housed.  Now we’re working on using that base for a materials check-in/check-out system when people come to the library.

What’s been exciting about GIS for you:  The exciting things are when I get Portal working and connecting web maps with configurable apps such as the newer tools like Survey123.  Then the data starts to flow and that feels really good, results happen for the division, and you know you are moving the ball forward.


As always, please submit a ticket to DNR IT Services for any GIS performance issues you'd like help with. Just include "GIS" in the subject line.
