File Format Selection

CSV Export:

• Equipment/CAD import compatibility for survey marks
• Spreadsheet analysis

DXF Export:

• CAD integration
• Technical drawing production
• Aerial imagery background

KML Export:

• Google Earth visualization
• Client presentations

Quality Considerations

Data Accuracy:

• Export includes source data accuracy limitations - be aware of the spatial/atrribute accuracy of the data before relying on it.
• Coordinate precision 
• Survey-grade information preserved· 
• Professional standards compliance

Area Limitations:

• Processing time increases with area size
• File size considerations
• Performance optimization
• Quality vs. coverage balance

CSV Export Purpose

Export survey mark data with  coordinate information for use in survey controllers, CAD software, or spreadsheets.

Setting Up CSV Export

Export Process:

1. Open the Tools Panel
2. Click the CSV tab from the tools panel
3. Select your export area by clicking “Select Area”
4. Draw a polygon by left clicking around the area you want to export
5. Configure your export settings
6. Click “Download CSV” to generate the file

CSV Export Options

Filtering Options:

• Min/Max Order - Filter marks by horizontal accuracy order (0-12)
• Boundary/Non-Boundary Marks - Choose mark types you want to include in your export
• Horizontal/Vertical Datum - Choose coordinate systems that your data will be exported in - note, this doesn't run a conversion for coordinates, so coordinates are only provided if the source dataset has coordinates in that system, this is particularly relevant with the vertical datum.
• Maximum 3000 marks per download

Format Options:

• Point ID - Custom numbering (sequential from Start Point ID) or LINZ Node IDs
• Column Format - 14 different arrangements available
• Exclude headers - if you don't want column names in your CSV file
• File Name - Set custom filename for download
• Null Height Value - an optional field to set a chosen height to all marks with no documented height

Common CSV Workflows

For CAD Import:

• Use Point ID format with custom numbering
• Include relevant coordinate systems
• Filter by accuracy requirements
• Match CAD software expectations

For Survey Equipment:

• Load info straight into your survey controller to get going in the field
• Match instrument coordinate requirements
• Use appropriate datum settings
• Verify coordinate format compatibility

For Analysis:

• Include horizontal/vertical order information
• Export comprehensive mark attributes
• Use consistent coordinate systems

DXF Export Purpose

Create professional CAD drawings with survey data, parcels, and aerial imagery for technical documentation.

Setting Up DXF Export

Export Process:

1. Configure layers - Turn on/off data layers in the layers panel to control what’s included in the map, note some layer groups aren't included in DXF export.
2. Select export area - Draw polygon around desired area
3. Set export parameters - Text height and coordinate system
4. Create Download - Processing may take several minutes

What’s Included in DXF Files

Survey Data:

• Primary and non-primary parcels with labels, including appellations, owners name, title number, parcel area.
• Survey marks with attribute labels
• Boundary dimensions (distance and bearing labels)

Reference Information:

• Street addresses and road names
• Basemap Layer (when DXF is small enough)
• Aerial Imagery Layer (where set in layers panel, and it intersects the survey) - in some cases you will need to load this geotiff into CADmanually, but it will be present in the downloaded ZIP file.

Technical Specifications:

• Maximum area: 200 hectares for processing efficiency
• CAD layer structure built in to easily isolate features by layer
• Coordinate system consistency

Professional DXF Tips

[IMAGE PLACEHOLDER: DXF-004] Caption: Before and after comparison showing layer optimization for DXF export

Preparation:

• Turn off unnecessary layers before export to reduce file size
• Plan export area to optimize processing time
• Consider end-use requirements

Quality Optimization:

• Understand the accuracy of spatial data before relying on it - this is particularly critical for boundary information.
• Include aerial photography for context and verification
• Maintain consistent coordinate systems
• Verify layer organization for CAD workflow

KML Export Purpose

Create KML files for viewing GRIP data in Google Earth, sharing with clients, or field reference.

Creating KML Files

Export Process:

1. Enable desired layers in Layers Panel - Only visible layers are included
2. Open the tools panel
3. Click the download KML tab
4. Zoom to your area of interest - KML exports current map view
5. Click “Download KML” - File generates immediately
6. Open in Google Earth - Double-click downloaded file

KML Content

Included Information:

• Primary and non-primary parcel boundaries
• Parcel appellations (legal descriptions)
• Geodetic marks, boundary marks, non-boundary marks
• Basic attribute information

Area Limitations:

• Maximum area: 6km wide by 3km tall
• Optimised for Google Earth performance
• Suitable for site-specific work

Best Practices

Client Sharing:

• Include appellations for property identification
• Focus on relevant area only
• Test file in Google Earth before sharing
• Provide basic usage instructions

Field Reference:

• Combine with GPS devices for site navigation
• Download to mobile devices for offline access
• Use for site verification and context
• Include relevant project information
