User Interface

Map viewer User interface

The Map Viewer is desktop GIS (geoinformation system) mapping and data editing window within Pantheon Farming.

The screenshot below presents the standard locations of the Map Viewer user interface elements as well as their names used further in this help system.

 

 

 

For detailed information refer to the following help topics and their subtopics:

Standard Toolbar (basic or expert)	The Standard toolbar provides quick access to the most frequently used Map Viewer features
Legend panel	The Legend panel is a window component holding the basic information about open layers and their visual properties. It consists of two tabs differing in  the information arrangement: Layers tab and Group tab. The Layers tab of the Legend panel displays the list of all open layers and the list of sections for each layer (if defined). The order of layers on the Layers tab determines the order of rendering on the Map Area. You can just drag and drop layer. You have to click and hld click for 1 seconf in order to begin draging. For detailed information about defining layer sections and layer visual properties refer to the  Layer Properties help topic. The Group tab of the Legend panel displays a fully customizable list of currently open layers divided into groups. The customization features are available in the Legend panel context menu.
Wizard section	The Wizard Section is a place where we will be leaded through some wizards during editing and queering spatial data.
Map area	The Map area is a part of the Map Viewer window where all the vector and raster data is being displayed and edited.
Tools/Result Window	The Tools/Result Windows is a part where different results of queries is being displayed or where different not most frequently features are being selected.
Data panel	The Data Panel is a window component which provides the means to preview  the attributes tables of the vector layers.
Status bar	In Status bar we can find different metadata regarding Map Viewer and its data.
Context menu	The Context menu group contains options available after right mouse click within the Map area or Legend Panel.
Scale panel	The Scale panel displays the scale of the extent visible in the Map area in the open project units. The scale is always computed for the center of the visible extent. The Scale panel is visible only when the open project has the coordinate system defined. To set, change or adjust the coordinate system of the open project, use the Select Map Coordinate System feature in Tools Window

 

 

Layer Properties Control

 

The Layer Properties dialog box contains a wide range of settings to control the visual appearance of a map layer.

Usage

This dialog box is organized into two panels:

• Left panel 
  Contains a tree of available settings. By selecting an item on this panel, appropriate detail settings will appear in the right panel.
• Right panel. 
  Detail settings.

The conent of panels depends on a type of layer and is lightly different for:

• Vector Layer,
• Raster/Pixel Layer,
• Raster/Grid Layer.

Common operations

This fragment covers operations that are common to all kind of layers, regardless of being a vector, pixel or grid layer.

The most important concept here is a section. The section always contains information about minimum and maximum scale of visibility. If the map scale is outside such defined scope, then the section will not be visible. This option provides an opportunity to set different rendering and visibility based on the actual map scale.

By using a toolbar over the left panel, a user can add, delete, delete all, and change the order of the section. Deleting all will leave one section with default parameters.

By using a toolbar below the left panel, a user can save and load all layer properties from/into .ttkstyle file. Thanks to that feature user can create a library of reusable styles.

General

The General node covers general information about the layer like path, name, coordinate system, etc.

 

 

Name	Description
Path	Path or URL to the layer.  [READ ONLY]
Name	Unique layer names.  [READ ONLY]
Caption	Layer caption.
Coordinate System	Current coordinate system for the layer, changeable with Coordinate System
Basemap	If checked turns layer(s) at the bottom of the project to basemaps. Which means that such layer(s) will be drawn continually upon dragging a map.
Cached paint	If un-checked turns-of caching layers(s) at the top of the map. Such layer will be then repainted upon each map repaint (even if visible extent remains intact. Generally, it is an option for handling trackable layers like live GPS positions etc.
Transparency	Factor defining the proportions in which the color of the foreground layer is mixed with the color of the background layer, Useful for creating anaglyph.
Info	Information about the layer, File format, resolution, etc.  [READ ONLY]
User comments	User provided information about the layer.

 

 

Sections

The Sections node summarizes information about sections visibility (active scale, additional query-based visibility for a vector layer).

Section

The Section node contains subnodes for specific layer properties.

 

 

Name	Description
Visible	Defines if parameters in the panel constitute visibility or invisibility of the section.
Minimum scale	Minimum scale of section activity. If empty then the parameter is ignored.
Maximum scale	Maximum scale of section activity. If empty then the parameter is ignored.

 

 

Vector layer

This is a description of the Layer Properties dialog box layout specific to vector layers. Use it to set colors, sizes, and labels for points, lines, and polygons.

Operations

List of all operation based on items in a left panel.

General

The General node covers general information about the layer.

 

 

Name	Description
Ignore shape params	If checked, visual properties embedded into some formats like DXF, DWG, MIF will be ignored, and full visual appearance will be set only by layer properties control.
Multipass rendering	By default sections are processed in a last-recently-used order to improve the speed. Therefore the order of sections are irrelevant. Check this option if the order of processing is important (eg. section first specifies road outline, then roads inside for a nice road junction rendering.
From Code Page	Program always uses Unicode. However, some layers are not encoded in Unicode.  This option provides a possibility to change layer encoding. Some layers (like DXF) will require reopening projects to acknowledge code page change.
Other parameters are common and are described here.

 

 

Sections
