After completing his degree in graphic design Ryan worked in a number of GIS positions, evolving from a focus on visual presentation of information into data management and process improvement, building user portals, interfaces, and systems to help integrate different applications. By the time he joined ORH in 2022, he had become an expert user of the two leading GIS platforms ArcGIS and MapInfo with fluency in SQL and MapBASIC languages, and a strong understanding of spatial data analysis requirements.

At ORH, Ryan works in process improvement automating GIS tasks in MapBASIC to increase the efficiency of core project procedures and reduce the potential for human error. He has built tools to that create networks and nodesets for projects, manage incident data, help with facility planning and produce maps that are visually appealing, easy to parse and consistent with ORH’s corporate style.

So far Ryan has developed the following at ORH:

• FACBAT, a tool for batching facilities and population data ready for linking into travel time matrices for use in the Facility Planning Model (FPM) used by SportsEngland.
• NETFIX, a program that converts raw highway data into ORH network tables that are used to produce journeys between stations and incidents.
• AGG, a tool for turning project areas into a dot matrix of nodes, integral for modelling
• MERV, a tool which assigns incident data to locations in these nodesets, helping with the understanding of demand
• LOCI, a tool for creating SiteSearch plans; heatmap-style visuals that indicate prime locations for new fire or ambulance stations to sustain and improve coverage
• BASER, a tool for automatically producing a base plan for use in reports to a consistent corporate standard
