Reset Classes

Requires an LP360 Geospatial Standard or above, LP360 Drone, or LP360 Land Standard license.

The Reset Classes tool is part of a collection of Cleanup Tools on the AI Classification Tab of the ribbon to help streamline the ground classification workflow.

The Reset Classes dialog helps you change classified points back to "Unclassified" (Class 1). This is useful when you want to redo classifications or fix mistakes.

Classes to Reset

Choose which types of points you want to reset:
 

Reset Edits (24)

• What it does: Clears the classification from points assigned to Class 24.
• When to use it: Use this when you want to discard manual interventions, macro corrections, or temporary flags applied during an editing session, reverting those specific points back to an unclassified state.

Reset AI Ground (23)

• What it does: Clears the classification from points assigned to Class 23.
• When to use it: Use this to remove the preliminary ground surface generated specifically by LP360's AI Classification engine. This is helpful if the AI routine produced undesirable results in a specific area and you need a clean slate to re-run the AI or use traditional ground filtering.

Reset Ground (2)

• What it does: Clears the standard LAS bare-earth ground classification (Class 2).
• When to use it: Use this when you need to re-run traditional ground extraction routines in an area, or if you are migrating from an older ground classification to a new AI-driven workflow.

Reset Outliers (18)

• What it does: Clears the classification from noise points (Class 18).
• When to use it: Use this if valid data (such as building roofs or variable terrain) was incorrectly flagged as high or low noise by a previous automated pass, allowing those points to be re-evaluated.

Reset All

• What it does: Selects all available classes within the targeted execution geometry to be reset.
• When to use it: Use this broad approach when an entire geometric space needs to be completely wiped of all classifications (reverting all points to an unclassified state) to start a processing workflow from scratch.

Execute

Choose where you want to reset the points:

By Layer 

Execute by Layer is an immediate execution tool that resets point classifications across the entire active LAS layer at once.

How it works:

1. First, check the boxes for which classes you want to reset (Edits, Ground, Outliers, or All)
2. Click the "By Layer" button
3. The operation executes immediately - no clicking or drawing required
4. A progress dialog appears showing the reset operation processing across all points in the active layer that match your selected classes
5. Once complete, all matching points in the entire layer are reset to unclassified

When to use it:

• Perfect for resetting an entire layer when you need to start fresh or correct a systematic classification error
• Great when you've run AI Classification and want to completely undo specific class results (like resetting all
• Ground points back to unclassified)
• Ideal when the problem is widespread across the whole dataset, not just isolated spots
• Most efficient when you need to reset everything at once rather than working area by area

Important Notes:

• This operates on the active LAS layer only - make sure the correct layer is active before clicking
• No preview or undo - the operation runs immediately on the entire dataset
• Use with caution - this is a bulk operation that affects all points in the layer matching your selected classes
• For more controlled, localized resets, use the Rectangle, Circle, or Polygon tools instead

By Rectangle 

This is a quick-click stamp tool that resets point classifications in a fixed-size rectangular area.

How it works:

1. First, check the boxes for which classes you want to reset (Edits, Ground, Outliers, or All)
2. Click the "By Rectangle" button
3. Your cursor changes to show a rectangular stamp outline (fixed size)
4. You can click multiple times to stamp different areas without having to re-select the tool

When to use it:

• Perfect for quickly cleaning up multiple small areas across your project
• Great when you have many scattered spots that need the same fix
• Faster than drawing individual rectangles when you need to hit the same size area repeatedly
• Good for systematic cleanup work where you're clicking through problem areas

By polygon 

Execute by Polygon is an interactive drawing tool that resets point classifications within a custom polygon shape that you draw on the map.

How it works:

1. First, check the boxes for which classes you want to reset (Edits, Ground, Outliers, or All)
2. Click the "By Polygon" button
3. Your cursor changes to a polygon drawing crosshair
4. Click on the map to place each vertex of your polygon shape

• Each click adds a corner point to your polygon
• You can create any shape - rectangles, irregular areas, complex boundaries

5. Double-click (or right-click and select "Finish") to complete the polygon
6. The reset operation immediately executes on all matching points inside the polygon you drew
7. The polygon disappears after execution, and you can draw another polygon without re-selecting the tool

When to use it:

• Perfect for irregular or custom-shaped areas that don't fit rectangles or circles
• Great for following natural boundaries like terrain features, property lines, or water edges
• Ideal when you need to precisely outline a specific area that needs class reset
• Most flexible tool for any size or shape - from small detailed areas to large complex regions
• Excellent for avoiding certain features by drawing around them

Tips:

• Zoom in for precise vertex placement on complex shapes
• You can create simple rectangles by clicking 4 corners, or complex multi-sided polygons with many vertices
• The polygon doesn't have to be perfect - you have full control over the shape
• Use this tool when the Rectangle or Circle stamps don't fit the area you need to clean up

By Circle 

Execute by Circle is an interactive drawing tool that resets point classifications within a circular area that you draw on the map.

How it works:

1. First, check the boxes for which classes you want to reset (Edits, Ground, Outliers, or All)
2. Click the "By Circle" button
3. Your cursor changes to a circle drawing crosshair
4. Click and drag on the map to create your circle:

• Click once to set the center point
• Drag outward to set the radius (size) of the circle
• Release the mouse button to complete the circle

5. The reset operation immediately executes on all matching points inside the circle you drew
6. The circle disappears after execution, and you can draw another circle without re-selecting the tool

When to use it:

• Perfect for circular or radial cleanup areas around specific features
• Great for cleaning up around individual objects like trees, poles, water towers, or storage tanks
• Ideal when you need precise control over the circle size for each location
• Excellent for spot corrections where each area might need a different radius
• More flexible than the Rectangle stamp when working with round features or radial patterns

Tips:

• Zoom in for precise center point placement
• You control both the location and size of each circle - drag further for larger circles
• Each circle can be a different size, unlike the fixed-size stamp tools
• Use this when you need circular areas but want to vary the size from location to location

By Feature Layer 

Execute by Feature Layer is an automated execution tool that uses the boundaries of existing vector features (polygons, lines, or points with buffers) to define where point classifications should be reset.

How it works:

1. First, make sure you have a feature layer loaded in your project (shapefile, geodatabase features, etc.)
2. Check the boxes for which classes you want to reset (Edits, Ground, Outliers, or All)
3. Click the "By Feature Layer" button
4. A dialog appears asking you to select which feature layer to use
5. The reset operation executes on all matching points that fall within or intersect with the feature geometries
6. The operation processes all features in the selected layer automatically

When to use it:

• Perfect when you have pre-existing boundaries that define your cleanup areas (parcels, building footprints, project boundaries, etc.)
• Great for batch processing multiple areas defined by features - each feature becomes a reset zone
• Ideal when you need to reset classifications within specific property boundaries or planning areas
• Excellent for GIS-integrated workflows where cleanup areas are already defined in shapefiles or geodatabases
• Most efficient when your cleanup areas are already digitized as features rather than needing to draw them manually

Examples:

• Reset points within building footprint polygons
• Reset points along corridor or buffer polygons around roads
• Reset points within property parcel boundaries
• Reset points in specific zones defined by planning features

Tips:

• The feature layer must already be loaded in your LP360 project before using this tool
• Works with polygon, polyline, and point feature layers (points may use a buffer distance)
• Processes all features in the layer - if you only want specific features, filter or select them first
• Saves time when you have many areas to process that are already defined as features
