Control Min/Max for elevation legend, shader, vertex editing, groups, etc.

dcoggin

My Christmas / New Years wish list for Global Mapper features:

- I like the feature to be able to scale elevation shaders to the loaded data, but I'd like to be able to fix a value and scale on both sides (above and below the fixed value). Usually I would use this is to set a blue / green boundary between water and low terrain at 0 elevation and scale the shader above and below.

- I'd like to be able to restrict the maximum and minimum elevations shown on the elevation legend. I often make presentation slides or report figures from Global Mapper displays, and I'd like to be able to have identical elevation ranges shown on several slides sometimes even though I have different elevation datasets shown with different min/max elevations.

- I'd like to be able to select a color to match a color at a particular point on the screen. When I load a large elevation dataset it might have a little blue in the ocean areas. Often I try to match my background color to that blue when I'm making a slide. I'd like to have a color picker to precisely match the color.

- It would be nice to have the legend editor integrated a bit with the overlay control center. I'd just like to be able to right click on a layer and have an option to add it to a legend if it makes sense (is a homogeneous layer).

- I'd like to be able to have a displayed list of existing groups appear when I select to add a layer to a group so I have a choice of adding to an existing group or creating a new group. It would be sort of like when I add a new feature to a layer I get a box to choose an existing layer or create a new one. There may already be a way to do this beside typing the correct current group name, but I can't figure it out. As a long term option, it would be nice to have a tree style control center with drag and drop.

- When selecting a vertex on a vector feature, editing the feature, then selecting Vertices..., it would be nice if the vertex coordinate display would scroll to display the highlighted vertex coordinates (so I can see the vector elevation).

Merry Christmas, Thanks for a great product.

David,

Thanks for the list.

For a fixed boundary in a custom shader, just add two entries, one at say 0.0 for water, then another at 0.001 (or anything just above 0.0) for green, then the transition between the values is so small that you won't even see it.

I will add an item to the todo list to restrict the elevation legend to a particular range.

To match a color from an elevation layer exactly, you could just do a quick screen grab then paste that in Paint or Photoshop and see the exact color.

I'll take a look at the other suggestions as well when I get a chance.

Let me know if I can be of further assistance.

Thanks,

Mike

Good news, I was able to get one request done already. Now if you have vertices selected on a feature and bring up the vertex dialog for that feature, those vertices will be selected and visible on the dialog to start with. I have placed a new build at http://www.globalmapper.com/global_mapper12.zip with the change for you to try. Simply download that file and extract the contents into your existing v12.xx installation folder to give it a try. If you are using the 64-bit v12 version there is a new build at http://www.globalmapper.com/global_mapper12_64bit.zip .

Let me know if I can be of further assistance.

Thanks Mike,

I understand how to make the land/water interface like you were saying. What I want to be able to do is to do that along with being able to select "Scale Shader to Loaded Elevation Values", and have a way to tie down the water interface to a set number so it's not scaled. I don't see any way to do that now. Thanks for the Paint tip on getting the exact color.

David,

Ah now I understand. I will add that to the todo list.
