System Panel

Overview

The System Panel opens a Settings dialog that centralizes all user-facing application preferences and maintenance actions. The dialog uses a left sidebar menu to navigate between sections, and supports dragging and resizing to fit your screen layout.

Sections available:

• Account — Displays your username and the current application version
• Map Settings — Controls theme, scale bar, layer creation, popups, and bookmarks
• Graphics Styles — Customizes the visual appearance of drawn shapes and analysis graphics
• Developer — Cache diagnostics and debug tools (only visible in development mode)

Opening the Settings Dialog

1. In the right toolbar, click the gear icon (Settings)
2. The Settings dialog opens as a resizable, draggable modal
3. Use the left sidebar to switch between sections
4. Click Hide Menu in the footer to collapse the sidebar and gain more content space
5. Click Close in the footer to dismiss the dialog

Account Section

The Account section shows read-only information about your current session:

• User — Your logged-in username
• Version — The current application version number (a DEV label is appended in development mode)

No changes can be made from this section.

Map Settings Section

The Map Settings section is organized into collapsible blocks. Each block can be expanded or collapsed independently.

Appearance

Controls the application color theme:

• Light — Uses a light background theme for the UI and map
• Dark — Uses a dark background theme for the UI and map

Theme changes apply immediately across the entire application.

Scale Bar

Controls how the map scale bar is displayed:

Unit — Choose the unit system for the scale bar:

Option	Description
Metric	Displays distance in metres and kilometres
Imperial	Displays distance in feet and miles
Dual	Displays both metric and imperial simultaneously

Bar Style — Choose the visual style of the scale bar:

Option	Description
Line	Simple line with end markers
Ruler	Segmented ruler-style scale bar

INFO

When Dual unit is selected, Bar Style is automatically locked to Line and the style selector is disabled.

Layer Creation

Controls how layers are added from the catalog:

Option	Description
MapImage	Prefer Map Image Layer when adding catalog layers
Feature	Prefer Feature Layer when adding catalog layers
Original	Preserve the source layer type as-is (default)

INFO

This setting can only be changed in development mode. In production, the control is locked and a notice is displayed explaining the restriction. Click Learn about layer types to open the layer concepts documentation.

Popups

Two independent toggle switches control popup behavior:

Enable all layer popups

• Immediately enables or disables popups on all currently loaded layers in the map
• Applies to both Feature Layers and Map Image Layers (including their sublayers)
• Use this for a quick bulk enable or disable across all visible layers

Default for new layers

• Sets the default popup state for layers added to the map after this change
• Does not retroactively affect layers that are already loaded

Bookmarks

Compact layout (hide thumbnails)

• When enabled, the bookmark panel displays bookmarks as a compact list without thumbnail images
• When disabled, each bookmark shows its saved map thumbnail

Sort order

Controls the order in which bookmarks appear in the bookmark panel:

Option	Description
A-Z	Alphabetical order, ascending
Z-A	Alphabetical order, descending
Newest	Most recently created bookmarks first
Oldest	Oldest bookmarks first

Graphics Styles Section

The Graphics Styles section lets you customize the visual appearance of shapes used throughout the application. Changes apply immediately to any new graphics drawn or displayed.

Click Reset All Styles in the section header to restore every category to its default appearance at once. This button is only active when at least one category has been customized. A confirmation dialog appears — click Reset to Defaults to confirm or Cancel to abort.

Style Categories

Each category controls the appearance of graphics used in a specific context:

Category	Used for
Target Layer	Primary shapes drawn for spatial analysis
Reference Layer	Comparison shapes and buffer geometry
Search Results	Highlighted features from search operations
MyLayer Graphics	Personal saved layer graphics
Uploaded Files	Shapes from imported Shapefile, KML, GPX, or CSV
Highlight/Analysis	Analysis result highlights and selected features
Measurement Tools	Distance and area measurement graphics

Click any category heading to expand it and access its style controls.

Style Controls

Each category exposes the following controls:

Fill Color

• Click the color swatch to open the color picker
• The checkerboard background indicates transparency support
• Adjust both the color and the alpha (opacity) channel

Outline Color

• Click the color swatch to open the color picker
• Controls the border color of polygons and the color of lines and points
• Supports alpha transparency

Line Width — Slider from 1 to 10. Controls the thickness of line features.

Point Size — Slider from 1 to 20. Controls the radius of point features.

Border Width — Slider from 0 to 5. Controls the outline stroke width for polygon and point features.

Live Preview

Each expanded category shows a live preview panel displaying how a point, line, and polygon will appear with the current style settings.

Per-Category Reset

A Reset button appears on each category heading when its settings differ from the defaults. Click it to restore only that category to its default values.

INFO

MyLayer Graphics and Uploaded Files do not show a per-category reset button — these are intentionally user-configurable defaults with no system-defined baseline to restore to.

Developer Tools Section

The Developer section is only visible in development mode. It provides cache performance testing and diagnostic tools for the internal layer caching system. All results appear in a dismissible notice panel.

The four tools are presented as a segmented control:

Segment	Description
Performance	Runs a side-by-side comparison of cached vs. traditional layer access timing
Validate	Checks whether the cache is consistent with the current map layer state
Stats	Shows total layer count, feature layer count, and cache hit/miss counts
Inspect	Displays detailed content of the cache, including feature and other layers

Click a segment to run it. Results are shown immediately in the notice area below. Click the close button on the notice to dismiss it and run another test.

Footer Actions

The footer is always visible regardless of which section is active.

Clear Cache

Clears all browser-stored cache data and reloads the application. This includes:

• Browser Cache API entries
• Browser local storage
• Browser session storage

A confirmation dialog appears before the operation runs. Click Clear & Refresh to proceed or Cancel to abort.

Use this action when you experience stale data, visual glitches, or settings that seem frozen.

Reset Preferences

Resets all user preference settings to their factory defaults and reloads the application. The following preferences are reset:

• Layer creation preference
• Enable all layer popups
• Default popup for new layers
• Theme preference (Light/Dark)
• Bookmark compact layout
• Bookmark sort order
• Scale bar unit
• Scale bar style

A confirmation dialog appears before the operation runs. Click Reset to Defaults to proceed or Cancel to abort.

INFO

Reset Preferences only clears preference settings. Graphics style customizations are stored separately and are not reset by this action. Use Clear Cache to remove all stored data including graphics styles.

Close

Closes the Settings dialog and returns to the map.

Hide Menu / Show Menu

Toggles the left sidebar navigation. When hidden, the content area expands to use the full dialog width. Click Show Menu to restore the sidebar.
