• Select by Mouse e. g. click on a feature, or select by a rectangle
• Query Builder provides select by attributes
• Buffer Selection queries one or more layer and select features in a user defined distance around a given selection
• Select Nearest searches one or more layer and select the nearest feature to the input feature.
• Select Contained searches one or more layer and select all features completely within the area of a given polygon.

Select by Mouse, also called Toogle select tool, combines a variety of ways to actively select features in the map, like picking a single feature, or selecting one or more features within a drawn rectangle. De-selection functionality is also provided.

The Query Builder, known by desktop GIS users, provides an easy way to build an attribute criteria based search string. Results could be added or substracted from previous selections. The selection can be variied by usual operators like +/-/</>/and /or/ not. To create the query select one of the fields and click apply, select the operator and than select the value and click apply. It is possible to edit the SQL string by hand in the command line of the Query Builder. Submitted queries follows in a resultwindow that inform the user about the number of hits. Moreover the features are selected and marked. Also here, there is the possibility  to save and load the created queries in order to retrieve the settings again.

The Buffer Selection tool provides the functionality to select features that reside in a calculated distance around a given selection. Select a layer with one or more selected features and enter the distance for search. Than select the target layer(s). Note that only layer marked as selectable in MyView are listet. The application will calculate regions with the radius of the given distance around every selected feature. This regions were used to select features in the target layer(s). Existing selections in the target layer(s) outside of the buffer will be removed. The resulting buffer remains till the user clicks the Remove-Buffer-Button.

Selects Nearest searches in one or more layers for the nearest object within a typed radius starting from a preselected feature. It is possible to search in multiple layers but results nevertheless in a single selected feature. The nearest feature from all target layers. Select a layer with one selected feature and enter the distance for search. Than select the target layer(s). Note that only layer marked as selectable in MyView are listet. The resulting buffer remains till the user clicks the Remove-Buffer-Button.

Select Contained makes a spatial query to select features within the area of a given polygon. The tool provides two ways for selection. One way is to select one or more polygon features in a layer and set this layer in the "Select Layers with selection (s)" field. Than choose the target layer(s) and click submit. Note that only layer marked as selectable in MyView are listet. The other way is to draw a polygon with the draw tool in the widget before submitting the query. In both cases all features that are within the area of the polygon will be selected. Existing selections in the target layers outside this area will be removed.

The Layer Manager is one of the most complex tool. It can be understood as a highly configurable TOC. Two separate presentations enable the user to display all available layers, select layers he is interested in and combine them to a set he will be working on afterwards.

The first presentation will be referred to as Available Layers. It lists all layers that are available to the currently logged in user. The layers are categorized into so-called datasets (group layers) and domains.

The first and most important step to perform analysis or views is the selection of layers. To find the best appropriate and available layer for your map the layers are categorized into domains and datasets. For each layer you can show metadata information. In addition you can search metadata for name or text in description.

My View

The second presentation is named MyView. In the MyView perspective the user has his own choosen subset of layers. He can  setting transparency or visibility on single layers and arrange the layers in the map. For each layer, legend symbols and metadata are provided. Furthermore, MyView is the place to determine which layers are selectable and editable by other tools. MyView represents the control- and information center for the added layers. The user is able to select setting for the map layout, get additional information and indicates presets for following processes.

Zoom to Coordinates

Zoom to coordinate provides an easy way to move the mapcenter to a known coordinate entered by the user. The latitude and longitude inputfields enable the user to quickly insert the coordinate in decimal degree like its shown in Show coordinates. The only difference is that up to 20 fractional digits are possible but not necessary.

Zoom to Location

Zoom to Location is implemented into the navigation panel and provides a quick and easy way to zoom to preconfigured set of well-known locations, Hot-Spots or Points of Interest. Three selectionfields are available:

• Governorate
• Neighborhood
• POI - Point of Interest

Global Net FX® Viewer is an instrument to display geographical and spatial information. Apart from being a mere viewer of information, it also provides a range of analysis and editing tools. It is developed as an application that is configurable and expandable, and offers multilanguage and cultural support. Additionally, there will be a user management system to define rights and roles, and a logging mechanism, to offer traceability of data changes. The application framework is built on top of a Google base map, which is loaded into the viewer.

• Integration of different applications in one Web-GIS Viewer
• Configuration and user management via Global Net FX Admin
• Multilingual user-interface (Arabic, English, German, ...)
• Fast viewer development
• Modular programming concept

 

• Layer Manager for project Data Management
• Query Builder
• Buffer Analysis Tools
• Selection Tools
• Editing Tools
• Reporting and Graphs
