Tutorial: Modelbuilder for ArcGIS + Data

Background

In general terms, a model is a representation of reality. A model represents only those factors that are important to your work flow and creates a simplified, manageable view of the real world.

ModelBuilder is an interface used to conduct geographic processing or geoprocessing functions in ArcGIS. It is part of ArcGIS’s core technology. Visually, it looks a lot like a flow chart. The power of ModelBuilder is that it allows users to automate geoprocessing functions on their data easily without writing any code. The visual nature of the interface makes it very easy to design and follow workflows and makes it a great tool for teaching students.

What is geoprocessing?

Geoprocessing is based on a framework of data transformation. A typical geoprocessing tool performs an operation on an ArcGIS dataset (such as a shapefile, feature class, raster, or table) and produces a new dataset as the result of the tool.

A geoprocessing tutorial can be found under the Tutorials in ArcView 8.x/9.x on the ESRI Canada website – http://www.esricanada.com/english/3552.asp, if you need a review.

Why build models?

Building a model helps you manage and automate your geoprocessing work flow. Managing processes and their supporting data can be difficult without the aid of a model.

Advantages of ModelBuilder

•    Visually representing workflow (excellent for students)

•    Automating workflows

•    Rerunning geoprocesses unlimited times with different data and parameters

•    Sharing models with other users

•    Exporting models as graphics for reports

It is easiest to think about ModelBuilder like a mathematical equation. There is an input or multiple inputs of data, an operation is performed on the input data that alters it in a certain way, and the data is returned as a new output.

In this Tutorial, you will learn:

 •    What is ModelBuilder

•    What you can do with ModelBuilder

•    How you can create your own model using geoprocessing tools

•    How to export a model as a graphic or as a script to share with others

Working with your PostGIS Layers using Quantum GIS (QGIS)

This tutorial will explain to the user how to connect QGIS to your PostgreSQL/PostGIS database and spatially view any of your tables containing a geometry column. PostGIS is a powerful database for GIS functions and data storage so it is nice to have a program to visually see the GIS data stored within the database.  QGIS is an easy to use open source GIS application and is ideal for data viewing, editing, and making maps. Si vous trouvez ce document utile et interessant merci de faire un don en cliquant sur un lien publicitaire dans le cadre  You are required to have a PostgreSQL database with PostGIS installed.   To install PostGIS you can visit the following website  This database will need a GIS table (contains a geometry type column). Follow the next few steps to import the shapefile to PostgreSQL using QGIS. Importing Shapefile Data to PostGIS using QGIS Open Quantum GIS and click the “Import Shapefiles to PostgreSQL"  button. This will open SPIT (Shapefile to PostGIS Import Tool). Start by creating a connection to your PostgreSQL database.  Under “PostgreSQL Connections” click the “New” button.  Add a name for your connection, and then enter the parameters for your database connection (Host, Database, Port, Username, and Password).  Click the “Test Connection” button and you should see a message saying “Connection to databasename was successful”.  Once this is successful, click OK. Select your server from the dropdown list and click “Connect”, a list of your schemas will appear in the Global schema dropdown menu.  Choose the schema where you would like to import the data. Now click the “Add” button and add your shapefile. Ensure the information is correct concerning the shapefile and click “OK”. Your shapefile is now added to your database. Next, we will view the newly added PostGIS data. Viewing PostGIS Layers using QGIS Click the “Add PostGIS Layer” button . This will open up a window. Under “PostgreSQL Connections” select your server name from the dropdown list and click “Connect”.  You will see a list of your PostgreSQL schemas. Open the schema containing your GIS data to see a list of all available layers.  Select the n_america layer click “Add”. The GIS data for North America will appear in the data viewing area. Use the “Zoom In” tool  to draw a box closely around the US, Canada, and Mexico. To view the attribute table for this layer, right-click the layer and choose “Open Attribute Table” or click the icon  when the layer is selected. To edit your data, turn on the editor by clicking the “Toggle Editing” icon .  Save your edits using the “Save Edits” button . A simple way to identify features or query the attributes of a location is to use the “Identify Features” tool . Click a location on the map to view its attributes. Classifying your Data Right-click the n_america layer and choose “Properties”. Under Symbology -> Legend Type, choose “Unique Value”. Under “Classification field”, choose “country” and click Classify. Each unique value in the country column will be given a random color. Click “OK”. Now let’s add some labels.  Select the n_america layer and click the “Labeling” button . Put a check next to “Label this layer”. Under “Field with labels”, choose “country” and click “OK”. This concludes our tutorial on working with PostGIS data with QGIS. The user should now know how to import shapefile data into a PostGIS database, load that layer in QGIS, view/edit the attributes, and symbolize the map according to its values.

What Is PostGIS?

PostGIS is an open source, freely available, and fairly OGC compliant spatial database extender for the PostgreSQL Database Management System. In a nutshell it adds spatial functions such as distance, area, union, intersection, and specialty geometry data types to the database. PostGIS is very similar in functionality to SQL Server 2008 Spatial support, ESRI ArcSDE, Oracle Spatial, and DB2 spatial extender. The latest release version now comes packaged with the PostgreSQL DBMS installs as an optional add-on. As of this writing PostGIS 2.0.0 is the latest stable release.

Geographic information systems, remote sensing and mapping for the development and management of marine aquaculture.
FAO Fisheries Technical Paper. No. 458. Rome. FAO. 2007. 125p.

ABSTRACT

Geographic Information Systems (GIS), remote sensing and mapping have a role to play in all geographic and spatial aspects of the development and management of marine aquaculture. Satellite, airborne, ground and undersea sensors acquire much of the related data, especially data on temperature, current velocity, wave height, chlorophyll concentration and land and water use. GIS is used to manipulate and analyze spatial and attribute data from all sources. It is also used to produce reports in map, database and text format to facilitate decision-making.

The objective of this document is to illustrate the ways in which Geographic Information Systems, remote sensing and mapping can play a role in the development and management of marine aquaculture per se and in relation to competing and conflicting uses. The perspective is global. The approach is to employ example applications that have been aimed at resolving many of the important issues in marine aquaculture. The focus is on the ways tools have been employed for problem solving, not on the tools and technologies themselves. In this regard, we consider GISFish, the UN Food and Agriculture Organization (FAO) Internet gateway to GIS, remote sensing and mapping as applied to aquaculture and inland fisheries, as a complementary resource to this technical paper.

The underlying purpose is to stimulate the interest of individuals in the government, industry and educational sectors of marine aquaculture to make more effective use of these tools. A brief introduction to spatial tools and their use in the marine fisheries sector precedes the example applications. The most recent applications have been selected to be indicative of the state of the art, allowing readers to make their own assessments of the benefits and limitations of use of these tools in their own disciplines. Other applications have been selected in order to illustrate the evolution of the development of the tools.

The main emphasis is on GIS. Remote sensing is viewed as an essential tool for the capture of data subsequently to be incorporated into a GIS and for real time monitoring of environmental conditions for operational management of aquaculture facilities. Maps usually are one of the outputs of a GIS, but can be effective tools for spatial communication in their own right. Thus, examples of mapping for aquaculture are included.

The applications are organized issue-wise along the main streams of marine aquaculture: culture of fishes in cages, culture of shellfishes and culture of marine plants. Both the recent and historical applications are summarized in tables. Because data availability is one of the prime issues in the use of spatial tools in marine aquaculture, a case study is included that illustrates how freely downloadable data can be used to estimate marine aquaculture potential and a section is devoted to describing various kinds of data. Because the ultimate purpose of GIS is to aid decision-making, a section on decision support tools is included.

Finally, we summarize our findings and reach some conclusions on the state of the application of GIS, remote sensing and mapping for the development and management of marine aquaculture.
