DATA ANALYSIS

One of the major projects undertaken by Spatialize in 2017 involved considerable data analysis and geoprocessing.  The project involved creating a new "catchment" layer based on historic paper maps from the 1960s and 1970s.  The catchments were then used as one of the input layers in a  geoprocessing model to assign categories and areas to the features of interest layer.  The goal was to be able to replicate the process as and when required and to be updated as new information comes to hand, with the resulting data used to update an existing database.

ASSET MAPPING

Earlier in 2017, Spatialize was contracted to update parks and recreation maintenance maps for the upcoming maintenance contracts.  It just so happened that the new aerial photography had also been released, enabling the assets data to be updated and tracks to be mapped and/or route altered.

PUBLIC ENGAGEMENT

Spatialize developed an online public engagement web application for consultation on the proposed camping in public places bylaw.  For the public engagement portion of the project, Dianne developed a web map application that enabled the public to place a pin on the map and register their feedback about the proposed sites.  Click here to view the "drop a pin" application.  Note that this map is no longer live.  Any new pins will be ignored.  For the final phase of the project, Dianne developed a simple web map enabling the public to find out where they can camp and where camping is prohibited.

NORTHLAND'S COASTLINE STORYMAP

Each year, the New Zealand Esri User Group provides an opportunity for GIS users to put their work up against their peers in the Great Kiwi Map Competition.  In 2016, Dianne was runner up with her storymap featuring Northland's Coastline.  Dianne created her storymap by pulling together public data and information on surf patrolled beaches, surf breaks, water quality and tourist information, on a selection of the best beaches in the North.  Click here to view the Northland's Coastline storymap.

PRECISION FARMING

A farm map was created to help the new spreader driver navigate the farm.  The map, uploaded onto the drivers GPS mapping device, shows the paddock layout, location of gates and farm tracks, as well as the spreading rates required for different areas of the farm.  This helped the spreader driver navigate the farm, reducing the spreading time as well as the cost to the farmer.  The map also identifies areas that could be hazardous for the spreader driver to navigate, and in turn providing a safe working environment for the spreader driver.

SOIL MAPPING

To support the fertiliser and farm mapping project, we undertook soil sampling.  The results from the soil samples would determine what fertiliser to put where and at what spreading rate.  Because the soil sampling would be repeated annually, we used a mobile mapping app for consistency and replication to ensure samples were collected from the same place each year.  The app also ensured that the soil samples were a representation of the different soil and pasture types across the farm.

3D VISUALISATION

Google has now made it very easy to visualise maps in 3D.  However, in 2000, Dianne was a pioneer in 3D visualisation with the developmenet of 3D fly through's for the Grampian National Park in Victoria, Australia.  Dianne was developing 3D maps in the days before the computer game Doom, Google and Esri made 3D visualisation popular.  The 3D model displayed here, was built using LiDAR DEM and LANDSAT satellite imagery.  It was groundbreaking in its time.

POPULATION GROWTH MODELLING

A major piece of work Dianne undertook while at the Whangarei District Council in 2006-2011, was formulating the Whangarei District population growth model.  This involved multivariate data analysis and spatial analysis to combine census data, planning zones and consent information to model potential future population, locate areas of growth and pressures on infrastructure, and modelling the population capacity for planning future infrastructure requirements.

SPATIAL PLANNING

One of Dianne's many strengths is the ability to understand planning requirements, to simplify spatial planning and to formulate the planner's vision into a reality. Dianne has spent many years working with planners, managing District Plan mapping and GIS systems for several local authorities, modelling the impact of plan changes on the environment and population, and adding value to Section 32 planners reports with statistical data analysis, spatial analysis and scientific information.
