Walkways and Cycleways
WALKWAYS & CYCLEWAYS

The highlight for Spatialize® in 2018, was mapping walkways, cycleways and mountain bike trails.  These projects involved a combination of desktop and field mapping.  The purpose of the projects varied, from submission of evidence for the District Plan appeals, to supporting application's to the Provincial Growth Fund to stimulate regional economy through tourism.

Automating data analysis in model builder
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

In 2017 and 2022, Spatialize® was contracted to update parks and recreation maintenance maps for the upcoming maintenance contracts.  Coincidentally, new aerial photography had been released in 2017, enabling the assets data to be updated and walkways to be mapped.

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.  

 

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
NORTHLAND'S COAST 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
PRECISION FARMING

In 2015, to apply GIS and precision farming practices to the family farm, Dianne created a farm map to help the new fertiliser spreader driver navigate the farm.  The map, uploaded onto the drivers GPS mapping device, showed the paddock layout, access points, location of gates and farm tracks, as well as the spreading rates required for the different areas of the farm.  This helped the spreader driver navigate the farm efficiently, reducing drive time and improving cost efficiencies. The map also identified areas that could be hazardous for the driver to navigate, and in turn provided a safe working environment for the driver.

Mobile field mapping
MOBILE FIELD MAPPING

To support the precision farming project, Dianne also undertook soil sampling, using a mobile field app to map the soil sample sites.  The results from the soil samples would then determine the most suitable fertiliser to improve nutrient balance for effective pasture and stock management.

Because the soil sampling would be repeated annually, Spatialize used a mobile field app to enable sampling consistency and replication.  By viewing the soil sample locations on soil and aerial photo basemaps, the mobile field app also ensured that the soil sample locations were a representation of the different soil and pasture types across the farm.

3D modelling
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 a series 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 and was showcased at the URISA and ESRI conferences in 2000.

Population modelling
DEMOGRAPHICS AND POPULATION 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
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.
