LandXML File for NSW
15 June 2014
GeoSurvey allows a user to prepare data for export of a sub-division plan as a LandXML file for
submission to the NSW LPMA, otherwise known as an ePlan.
The subdivision calculations can be done using a local origin for coordinates or they can be
done using MGA coordinates and ground distances.
If the subdivision calculations are performed using a local origin, then the job should be
transformed to MGA and the job datum set before exporting the LandXML file.
In NSW, survey plans of subdivision can be lodged either as a physical plan, as a LandXML
document or they can be lodged in both formats. If the LandXML document contains all of the
information to be shown on the plan, then a physical plan is not required. The LTO will draw
the plan using their rendering software and their plan will be the one actually lodged.
Processing Steps
Overview
1. Initial Setup - Config File
2. Create the Plan heading Information
3. Integration Survey Marks
4. Point Data
5. Plan Data
6. Parcel Data
7. Editing Parcels and Lines
8. Occupations
9. Export to LandXML file
Overview
After the subdivision and surrounding survey data has been generated using the usual COGO
techniques in Geosurvey:
- Create a Plan (DPnnnnn) using the new Edit/Plans/Add Plan option and fill in all the normal Plan Form data.
- Form strings for all the other lots around the plan where needed. Each string can be for the full surround of the lot or for part of the full lot.
- Add strings for connections to RMs and Integrated Survey Marks and connections between parcels where needed.
- For Control Points (SSMs and PMs - survey integration marks) use the new Points/Control option to create Control Points.
- If the job is not using MGA coordinates, use the survey coordination marks (the control points) to transform it to MGA in the appropriate zone and set the job datum and zone.
- Points - For survey marks (RMs, pegs etc), go to each one with "Point Properties" and set the Extra Attributes.
- Form strings and points for all occupations and set the extra attributes for each string and point.
- Create the Parcels using the new Edit/Plan/Add Lots to Plan option to convert the lots to parcels on the plan. The parcels will have rounded dimensions according to LTO rounding rules for bearings and distances. They will also use ground distances, not grid distances.
- Use Conversion/LandXML export to write out the LandXML file for submission to the LPMA.
- You can use the LandXML Import option to test the LandXML file by importing it into a blank job.
