Tutorial QGis 2.8 graphical modeller

In this tutorial, we will address the automation processing chains with QGIS processing modeller. 
We will see how to set, edit, document and run a template. You will learn how to add data input and processing algorithms in a model. We will, also, discuss how to run the models iteratively as well as how to fit them together in others, and how to perform the models in batch mode.

Firstly, we will introduce the modeller and explore the various types of inputs and algorithms available for the models. Then, we will discuss, using examples step by step, how to develop a model that can be added to the processing toolbox.  Continue reading “Tutorial QGis 2.8 graphical modeller”

ArcGis Pro 1.0 Update: a small collection of nasty surprises 28/05/15

You have installed 1.0 and started watching this new tool. You will discover a lot of good things, more or less obvious at first sight. But also, little by little, some small (or big) bad surprises.

We have listed right here some. Since the list is not necessarily complete , we will update it regularly .

Here is  the list as of 28 May 2015:

Cannot access and use SpatiaLite databases

ArcGis Pro does not recognize. sqlite files, even those created with ArcGis Desktop. Like the dlls required are  included in ArcGis Pro 1.0 you can  expect they  will be accessible in the next version of ArcGis Pro ( or not).

Cannot use another address geocoder but the one provided by ESRI

For the time being it is not possible to disable the default geocoder. You can add local geocoders but you cannot make ArcGIS Pro use them instead the standard one.

No hooking grid in the page layout window 

To put in place the different elements of the page layout, you will only have the installation properties of each object. No rules, no guides, no hooking grid. They are promised for the next version…

———————————– 
Here is the list at 30   April 2015:

Labels and annotations? No, just labels

For now, ARCGIS Pro supports only the labels on the fly. You have no way to convert them in annotations, with all that that it includes. If you are not satisfied with the position of your labels , you must leave to return to ArcMap and build it the old way. By cons, if you cannot create  or edit them in ArcGis Pro, ArcMap annotations can  be loaded and viewed in ArcGis Pro.

Cutting the data block on the fly 

If you use this option for an adequate result of your page setting, be aware that the possibility does exist in ArcGis Pro. Nevertheless, the extra option to add exceptions does not, yet, exists. For a detailed example, refer you to the article   ArcGis Pro 1.0 Tutorial English : 4.1 – migrate an ArcMap document .

Block layout data on page

You have to know that there are unfinished sections! In the page setting, all that corresponds to the tab Gridlines in the properties window of the ArcMap data block , does not exist yet. You cannot perform neither Graticule nor Grid nor Landmarks . 
And there, frankly he there is not much to do to solve the problem. I will not repeat the advice found on an ESRI forum to make the grid with ArcMap, convert in graphics and import to ArcGis Pro, the changes  being managed automatically by you by leaving and returning to ArcMap ???

————————————————– —- 
Here is the list such what was at April 5 , 2015

You cannot add connections OGC (WMS, WFS, …) in a project

If you are used to work with OGC connections, there’s no way to open a new project and make the connection to the services. A next version should add this feature.

For now, we can get around this problem by knowing that if you open with ArcGIS Pro an ArcMap document depicting connections, they are used in ArcGis Pro. What is missing is not the use section of the OGC connections, it’s only the configuration section of the connections.

Instead of opening a new ArcGIS Pro project, start by creating a map document with your configured connections and import the document to ArcGis Pro.

You cannot load an Excel table in ArcGIS Pro 1.0

Astonishing, right? But true. If you “Load data” and you browse your directories, you will not find Excel files.

To get around the problem you can import the Excel table into a geodatabase table. You use the ”   Import   ” tool from the toolbox “Data Management   »->   »Excel   “

Invisible Directories

This is a bug rather than a tools missing problem. But since this can quickly turn into a nightmare, be warned. Sometimes you want to load a layer and you are desperately searching for the repertoire. You see your tree but where your directory should be present, it is not. Until this bug is resolved, in the name window of the layer to be loaded, type the full name of the file with its path. This will load your layer.

No animation available in 3D views

Everything about the 3D overview  and  animation creation is not yet coded in ArcGis Pro. So, no way to bypass this problem. So, you will have to wait for  a future version to have a 3D  levelview of what is feasible with ArcSCene .

Statistics of a field table

In ArcMap you have the option “statistics” in a field name in the attribute table. This allows you to see “on the fly” the min and max values , the  total sum, etc. , for the column or records selected . This option does not exist in ArcGis Pro where you have to go through the geprocessor to create a statistics table of the field.

No georeferencing tool

If you use the georeferencing ArcMap toolbar, do not look for an equivalent in ArcGis Pro. For now (maybe in a future version) you have a Toolbox tool , very , very rudimentary .A workaround: continue to georeference your rasters with ArcMap.

Search a value in a table

In ArcMap you can use the Ctrl-f sequence to search a value in a column of a table. For now this function is not implemented in ArcGis Pro.

Seeing a TIN in the 3D view, not possible

If you work with TINs, you can load, see and use them in a 2D view in ArcGIs Pro. 
Regarding the 3D view, you can use a TIN as reference surface, but you can not visualize it.  You cannot charge it as a 3D layer. 
Solution: in a next version.

Editing the topology in ArcGis Pro: Not for the time being

The set of editing tools for the topology are missing. We will have to wait that a future version do have it .                                 

ArcGis Pro 1.0 Tutorial English: 4.3 – adding a layout

If the creation of a map is relatively close to what we do in ArcMap, for the creation of a layout a non-negligible intellectual exercise is required. The ArcGis Pro Ribbon allows you to re-group commands that are a bit scattered in ArcMap. The only place where we can say everything is pretty much grouped is the Layout section of ArcMap. In ArcGis Pro you will wander from tab to tab and from button to button … So let’s get what it takes and attack the ArcGis Pro Layout.

Firstly I propose to discuss the conceptual differences of the Layout compared to what you know about ArcMap, and, finally, considering an example. Continue reading “ArcGis Pro 1.0 Tutorial English: 4.3 – adding a layout”

ArcGis Pro 1.0 Tutorial English: 4.2 – create a map

We have discussed in the previous article ( ArcGis Pro 1.0 Tutorial English : 4.1 – migrate an ArcMap document) how to import an Arcmap document to ArcGis Pro. Here we will discuss how to create a map using a blank project. 
  First, start ArcGIS Pro and select BlankProject. Then, in the INSERTION tab, click on the button New Map

Now, you have an empty map on your cartographic view. Continue reading “ArcGis Pro 1.0 Tutorial English: 4.2 – create a map”

ArcGis Pro 1.0 Tutorial English: 4.1 – migrate an ArcMap document

We have discussed the different types of map displays available in ArcGis Pro (ArcGis Pro 1.0 Tutorial English: 4 – Cartographic Views) . We will look in more detail at each type of display, starting with the migration of an ArcMap document. We chose a complex document that uses a lot of ArcMap options: personal symbology, variable footprints, a template created with Production Mapping, a complex layout… Continue reading “ArcGis Pro 1.0 Tutorial English: 4.1 – migrate an ArcMap document”

ArcGis Pro 1.0 Tutorial English: 2- the Project ArcGIS Pro PROJECTS

The ArcGIS Pro application lets you gather all the resources you need to complete a project in one place. A project contains maps, layouts, server tasks and connections, databases, toolboxes, folders, styles, and so on. It can also integrate content from your portal or ArcGIS Online of your organization.

Projects can be created on your local file system and shared online as a   project package. These Online Projects can be downloaded to your local station. Continue reading “ArcGis Pro 1.0 Tutorial English: 2- the Project ArcGIS Pro PROJECTS”

ArcGis Pro 1.0 Tutorial English: 1- Interface Discovery

We will begin a series of tutorials for the new application available with ArcGis 10.3, ArcGis Pro.

This first chapter is dedicated to the discovery of the interface.

What’s up?Ribbon!

 

ArcGIS Pro uses a rectangular ribbon at the top of the application to display and organize its features in a series of tabs. The ribbon only shows the tools that are relevant to the current task. Rather than taking up space on the screen to display a series of toolbars-some of which you cannot even use-the ribbon is contextual and updates to reflect current work opportunities. In this way, ArcGIS Pro can provide a large number of features in a simple way, without overwhelming you. When you have an open map, you simply see the commands that work with maps. The ribbon tabs appear as you need them, such as the specific tools for the raster layers that appear when you work with this kind of data. Continue reading “ArcGis Pro 1.0 Tutorial English: 1- Interface Discovery”

Terrain Tools for ArcGis 10.3 and ArcGis Pro

Standard techniques for representing the terrain, such as shading, are sufficient for many applications, but with Terrain Tools you can represent the terrain under different lighting conditions, or use more artistic techniques. This set of tools complete or extend what you find in the default software. These techniques are often difficult to find or to put into work. The Terrain Tools project brings together some of these ideas in a toolkit which provides the features to create alternative representations of the terrain with ArcGIS.

The Terrain Tools are included in a toolbox to be used either with ArcGIS Desktop 10.3 or ArcGIS Pro 1.0. Continue reading “Terrain Tools for ArcGis 10.3 and ArcGis Pro”
