Topo Optimiser


Style your Topo data and output it in the best format to suit your needs.


The Topography layer from OS is the most comprehensive map dataset of Great Britain, making it a fantastic resource for referencing your data against real-world features. However, receiving the data as GML isn’t ideal as the detailed attributes are pretty inaccessible. What’s more, styling the data to make it easier to interpret can be a time consuming process.

That’s where our Topo Optimiser comes in.

The Optimiser processes the data by parsing the unusable Topo GML and a parameter file together, resulting in styled mapping with accessible attribute data for use in other applications. The Topo Optimiser then outputs the data as your choice of spatial (SHP, TAB, MIF/MID) or AutoCad (DXF, DWG) files which can then be loaded into your GIS or CAD system.

Store your data on a database? No problem, you’re also able to upgrade our Topo Optimiser to include the ability to store on an Oracle, SQL or Postgres database and write out to spatial or AutoCad formats. You’ll even be able to write back to a different database as many times as you like, with different settings each time. Contact your Account Manager for more information.

How it works

  • Launch the App in the DataFlow Player
  • Upload your Topo data
  • Process your data
  • Output the optimised files

The much anticipated Topo V9 is here – but what does it actually mean for you? There is an abundance of new descriptive terms that give you even more ways to use the data, but the range can be bewildering. Below, we’ve tried to make it a bit simpler - so here’s an overview of what we think are some of the most beneficial updates:

Land-usage Land Usage

Additional descriptive terms have been added that make analysing and understanding land usage easier and far more useful. Whether you’re looking to establish land usage ratios across your area or planning for future development projects, terms such as “Agricultural Land” and “Landfill” will help you to paint a clearer picture of your region, enabling well-informed decision making.

New terms: Agricultural Land, Slag Heap, Landfill, Spoil Heap, Mineral Workings, Wind Turbine


Waterways & Coastlines

Access to waterways and coastlines is becoming even more important with an increase in water-based leisure activities, not to mention the need to access waterside structures for maintenance purposes. The new set of terms will help you differentiate between types of waterways and foreshore types so that you can make the most informed decisions about access to your inland and coastal waterways.

New terms: Canals, Mooring Posts, Locks, Weirs, Bridges, Foreshore types eg Sand, Shingle, Mud


Civil Contingencies

Civil Contingency planning is all about maximising your response to emergency situations. By making you aware of all of the resources available to you, the new descriptive terms provide you with a far fuller view of how an emergency site can be access and managed. Whether it’s routing, access, resources or communications, these added terms provide you with valuable additional insight.

New terms: Electricity Sub Station, Signal, Emergency Telephone, Ford, Gas Governor, Level Crossing

Is that all?

Well, we’d be fibbing if we said that’s all that has changed, but we think these are the most useful bits. If you’re really really interested, here’s our mini overview of some of the less exciting changes (don’t say we didn’t warn you):

  • English has been removed as the default language to allow for accepted place name in alternative languages such as Welsh
  • Changes to the way chunkingPolicy and chunkSize are defined within the QSQueryResult.xsd
  • The schema now includes the latest GML 2.1.2 files

The TopoOptimiser Oracle Database Module (TOOM) consumes the native GZ files produced by Ordnance Survey (OS) for its OS MasterMap (OSMM) Topo Layer product and adds the styling and optimisation attributes from the standard TopoOptimiser App.  It then loads the entire dataset into a spatial Oracle Database in an optimised manner.

TOOM can then extract the data from the Database according to a range of parameters and output in fully styled data files in .TAB, .DWG and .DXF formats as well as un-styled data files in .SHP.

TOOM is expected to be used to maintain a current and accurate version of OSMM Topo Layer in an Oracle Database.  It is then expected that multi-user applications connect to the Database to consume the data.

Topo Optimiser Oracle Database Module 2.12.1


- Improved creation of spatial metadata when loading into Oracle and indexing. This now allows for viewing the data held within the database with a GIS application
- Enhanced indexing of tables within Oracle for extracting to tiled GIS files
- Improved handling of text layers that contain special or combined characters (for example ä, é, ã) so these can be extracted fully.

Topo V9 is on the way, and all the updates sound great – but how can you use it to your advantage?

Let’s imagine that you’re looking for the perfect site to develop a new coastal resort. The big question is; where do you put your beach huts?


First things first

Before you begin, you need to work out what your visitors are looking for – their list probably looks something like this.

So out go the rocky beaches and working harbours...

But where does Topo V9 come in? Simple; it makes these areas much easier to query and locate.

So how does Topo V9 help?

You know that some new descriptive terms have been added, and you know that these can help you with your decisions by making features easier to locate, but how?

By adding new terms and separating out others, you can derive more value from you Topo data. Take a look at the maps below; the left is derived from Old Topo, and on the right is derived from Topo V9. By defining the different foreshore types, you can tell which is which at a glance – useful isn’t it?

Old Topo Topo V9
Topo before Topo V9

And that’s just one example - imagine knowing where agricultural land or industrial waste sites lie. The possibilities are endless!


Topo Optimiser Translate Version 2.12.1


- Improved creation of the Catalogue table for tiled output. This allows for greater interrogation of the dataset
- Enhanced ability to translate 2km chunked input files
- Re-engineered tiling process to create all GIS tiled formats

New Features
- No new features have been added in this version.
