There is an increasing co-work between ArcGis and
Excel. Indeed, the information management is infinitely richer with
a spreadsheet such as Excel than with an ArcGis tabular view.
has always been possible to load an Excel table in ArcMap. But since
version 10.2 there are two tools that allow you to create an ArcGis table from
Excel and another that allows you to create an Excel table from an ArcGis table.
These tools are also present in ArcGis Pro.
We will discuss how this works.

We have already discussed the 2D entities extrusion to create 3D views in the article How to transform your data from 2D to 3D to fully exploit ArcGis Pro 1.0? 2 – With 3D layer towards class entities .
In that article we created a 3D view with ArcScene from the “building” layer of the cadastre by using the property extrusion available in the properties layer window.
We will right here perform the same operation, but with ArcGis Pro. This
will let us visualize how the 3D work integrates, without resort to another
application simultaneously (ArcMap ArcScene).

In the previous two articles, we have discussed ( How
to use Landsat images (free) with ArcGIS (ArcMap) for NDVI , How
to use Landsat images (free) with ArcGIS Pro for NDVI ) the calculation and
display of NDVI with ArcMap and ArcGis Pro. In this article we will
discuss how to achieve this
download Landsat images from Earth Explorer, check out
to use Landsat Images ( Free ) in your GIS .
Here we will use the raster calculator to calculate the NDVI
, then we will discuss how to create and use a specific colour
gradient for this index.

If you work with a Landsat 7 image,
you will load in QGis the bands 3 (red) and
4 (infra-red). If you work
with a Landsat 8 image you will load the bands 4 (red)
and 5 (infra-red).
In the previous article, How to use Landsat Images ( Free ) with ArcGis (ArcMap) for
NDVI, we have dealt with the calculation and display of the NDVI
index with ArcMap.
Here, we will discuss how to achieve the same operation
with ArcGis Pro. We will start by using the composite image , created with the
tool ” Composite channels ” also directly available at the ArcGis Pro

In a previous
article, How to use Landsat images (
free ) in your GIS , we discuss how
to download Landsat 7 or 8 images. Now we will discuss
how to use them with ArcGis, when you use ArcMap or ArcGis Pro.
We left at the point where you had , in a
, a series of 8 or 11
tiff images. Each of
them corresponds to a satellite band .
Landsat 7 images have 8 bands
while the Landsat 8 have 11.
For the calculation of the NDVI
the band corresponding to the red and the

We will continue discussing those little details
worth knowing to be able to switch from working in ArcMap to ArcGis Pro.
In ArcMap, you display the attribute table
with the right click on the layer in
the legend window and open the table , or
clicking on properties -> fields to view and edit
the table structure.
In ArcGis Pro, just the first
. If you want to work
on the structure of the table you must use the following option
the layer menu : “Design” then “Fields” ( or Domains, or
Subtypes if you must
action on them ).

There are always two psychological barriers to overcome with Model
Continue reading “ArcGis Model Builder: Expanding a Model to an Input Dataset”
- the first one is deciding to,
actually, use it and move from the interactive, natural working mode to ArcMap,
i.e. to a working mode where all the workflow is performed virtually, before
actually launching it
- the second, when you are,
already, comfortable with the tool and start creating increasingly complex
models, but always based on an input layer producing an output layer. And then, you think it would be nice to be able to
apply the model automatically to a whole batch of input data, and somehow you
find out that it is necessary to use “iterators”.
To continue getting familiar with ArcGIS Pro, in
this article we will discuss how the Model Builder
is introduced in the new interface.
We will consider an example quite
simple: With the INSEE (200m) statistical rectangles data, we will
buffer zones around a site every 500m.
Basic data is presented as follows:

We have already discussed two types of iterators, the layer iterators ( ArcGIS Model Builder: how
to spread a template into a dataset in input ) and the digital iterators ( ArcGIS Model Builder: FOR and WHILE
Therefore still remains the last type of iterators: entities iterators.

The “ArcGIS Editor for OpenStreetMap” toolkit lets you use
ArcGIS tools to work on OpenStreetMap data. This set of tools for ArcGIS 10.X
allows you to load OpenStreetMap data and store it in a geodatabase. Afterwards,
you can use the ArcGIS Desktop editing environment to create, edit, network
scan, or update data. Once editing is completed, you can post changes to OSM to
make them available to all OSM users.
