We will devote some articles to this ArcGis application for those who
want explore it or start a true project .
Most of ArcGis Pro deals with projects where coexist 2D-3D. Except for
the ArcScene followers, most ArcMap users
are confined to 2D views , even when they work with data in excess of 2
dimensions such as the NCDs.
We have already published a series of articles that address the topic of
how to convert 2d data to 3D data:
Now we are going to consider an example and follow the procedure with
ArcGis Pro. We will use the data and example from the article3D – Functional surfaces – Coastal specific case (sea-land interface), since it, also, allows to consider the basic
working methods with ArcGis Pro.
We have two data sources to generate our DEM:
an SRTM raster for the terrestrial area
an isobaths layer for the marine section .
have a Bing aerial image for the Conquet area that we want to see in 3D, draped
over our DTM
Then, we will build a continuous land-sea DTM with ArcGis Pro.
How to define the earth and sea domains
Being given that we have different sources and processing for the data
located on earth or in sea, a prerequisite is to define the boundaries between
the two domains .
To this end, we will use a
classic layer (Coastline common IGN-SHOM) and a surface rectangle of our study
- Open ArcGis Pro and select a Local Scene type new project.
ArcGis Pro opens with a 3D view and a default layer (Topographic)
- Click the Insert
tab and the button NewMap
The 2D view is added to the map.
You can remove the Topographic layer
Load you 2D layers in the 2D view : Map tab , Add Data button
You can see that the window has 4 different areas :
- at the top: the ribbon with menus and command buttons
- left: the legend window, similar to ArcMap
- center: the view window with a tab for each available view
- right: the
We will carry out a simple task : create a polygons layer with terrestrial
and marine polygons.
We have a terrestrial layer and a delimiting rectangle. If we perform the union
of these two layers, we will create one or various polygons Additional terrestrial
polygons fill the surface. These new polygons will correspond to the sea.
In order to perform this operation , we must find the Union tool in the
Toolbox and execute it .
In the Geoprocessing window , click Toolboxes (
next to Favorites )
You can see the classic Toolbox window of ArcMap .
