ISOM Conversions & IOF Mapping Conference

ICOM 2018 Presentation

Easily convert symbol sets

Convert an existing file

  1. open your source (e.g. ISOM 2010) map
  2. save as with new name
  3. Map > Symbol Set Conversion…
  4. enter the target symbol set
  5. select the relevant crt file (e.g. ISMTBOM 2010)
  6. displayed in left list are source symbols and in right are target symbols
  7. for any unticked source symbols, complete or leave the target symbol
  8. OK
  9. in new map, Select > Select Objects by Symbol > Objects with unknown symbol, to identify symbols that were not converted.
  10. further information http://www.ocad.com/wiki/ocad/en/index.php?title=Symbol_Set_Conversion

Conversions available

Two step conversions

Some conversions such as OSM to MTBO do not have ready made crt files. Using a plain text editor you could create your own crt file perhaps using one of the existing ones as a base.

OSM to MTBO

If using the New Map Wizard to create an MTBO base map, you need to use a 2 stage process as there is no OSM to MTBO crt file.

Create the base map with ISOM 2017 as the target. Then use the Symbol set conversion process to get the base map to ISMTBOM 2017 symbols.
See my post on using the New Map Wizard to create base maps.

International Conference on Orienteering Mapping 2018

Presentations by OCAD Inc Staff

There were two presentations by OCAD Inc staff.

Hubert Klauser’s presentation covered two topics;

  • generalising orienteering maps with TPI contours
  • using the Check Legibility tool

Gian-Reto Schaad’s presentation was on Semi-automatic Extraction of Near-ground Vegetation from Lidar Data

School map symbols

School map from Mapping Commission work group (nice design!)

The IOF Mapping Commission presented their proposals for school orienteering map symbols.

It is interesting to see the variety of symbols currently in use for typical school objects.

Colours for the colour vision impaired

Adrian Uppill was a co-developer of a presentation on Solutions for orienteers with colour vision defects. If the Eureka Orienteers’ permanent orienteering course in Daylesford, VIC completes its funding, Adrian’s work on this topic will be put into practice.

OCAD tools to create base maps

Towering cumulus over Leanganook

New Map Wizard

2018

Use New Map Wizard to quickly create a georeferenced orienteering base map. Even correctly oriented to magnetic north if you like. The process uses Open Street Map (OSM) and converts to your selected OCAD symbol set. You can easily add more symbol translations to the CRT translation file.

Simply want to georeference a new blank base map or any existing map? The process is much the same but use the resultant georeferenced map as a background map to georeference. Generally OSM major road junctions are best and they don’t have to be on the orienteering area.

WMS Server

2018, 12, 11

WMS Server (under Background Maps in menu) is a fast and efficient way of obtaining base map data in the form of background maps or map data.

A 12 minute mp4 video of the process using LandTasmania Spatial Web Services as an example, can be downloaded from Google Drive. (Unfortunately an audio issue with online Screencast prevents easy online viewing).

OCAD & Mapping Snippets

OCAD reminders

Some tips that tend to be overlooked.lightbulb

40%, 20% discounts ending

And another tip – the big discounts for updating OCAD 12 or 11 to 2018 finish at the end of next month. If you have been thinking about it, I suggest you either do it or diary it.

Team OCAD edition image4 clubs benefit from Team licences

Four clubs have taken advantage of the opportunity to acquire Team licences. In three of those clubs, some club members transferred their licences to the club. Then the club traded each licence in for two Team licences.

Massive savings, significant flexibility. Check out my recent post Hidden Value in OCAD Team Editions for more info.

GIS file conversions

A conversation that crops up more frequently in the lidar era is how to convert a file from one format to another. The FME Integrations Gallery may have the answer for you.

Conversion categories include CAD, GIS & Mapping, Lidar & Point Clouds. The Cloud version appears reasonably priced for say a state orienteering organisation. There is also possibilities for free versions.

Open source PDFsamDocument

Frustrated at the limitations of Adobe Reader and can’t justify Adobe Acrobat? Then take a look at the open source PDFsam.

PDFsam Basic is free and enables split, merge, extract pages, rotate and mix PDF files.  PDFsam Enhanced comes in 3 flavours giving you even more options at a reasonable price.

QuestaBird

Your kids looking for something more to do while waiting for you to finish the course? Or vice versa? QuestaBird is a mobile based adventure game with a purpose. Use your phone to photograph birds, butterflies and moths,  competing with others to collect the most species and the greatest number of animals in your area.

“Players are not only learning about their environment, they’re collecting data that helps protect it.  In effect they have become citizen scientists without even knowing it.”

Downunder geospatial awareness ratingsgeospatial

Australia is ranked 14th and New Zealand 25th in terms of geospatial industry awareness according to Geospatial Media & Communications.

Criteria are data infrastructure, policy framework, institutional capacity, user adoption levels, industry fabric (whatever that means).

The top 10 starts with USA, and apart from Singapore, China and Canada, comprises European countries.

Hidden value in OCAD 2018 Team editions

An even closer look at OCAD 2018 valueOCAD Orienteering edition image

Before  the release of OCAD 2018 in March, I wrote a warts and all post on the features and value of OCAD 2018.

Since then I have become aware of a significant value that may not be readily apparent to current personal users and their clubs.

Achieve lower cost & greater flexibilityOCAD 2018 Starter edition image

Clubs could approach their members who hold OCAD licences with a view to transferring their licence to the club. Continue reading Hidden value in OCAD 2018 Team editions

New OCAD Lidar Features Example

Cornish Hill lidar vegetation height image

ELVIS lidar data processed through OCAD 2018 DEM import

Mark Roberts recently reported

Just a note that I recently downloaded some lidar data from ELVIS and imported to OCAD 2018 and the results are spectacularly good. The vegetation height function depicts clearings and buildings perfectly:

Mark’s OCAD 2018 import from ELVIS Lidar

Mark later remarked that lidar is becoming very readily available and the OCAD processing of lidar is so easy.

VIC lidar data processed through OCAD 2018 DEM import

Following Mark’s report I received ordered lidar data for a permanent orienteering course in Daylesford, VIC. Here in VIC we do not yet have free access, however on behalf of Orienteering Victoria I have established a protocol with DELWP for access to lidar data. As their paid orders take priority it takes some weeks to fulfill an order but the wait is certainly worthwhile.

I processed the ‘irregular points’ las files through OCAD 2018 DEM import wizard, selecting all options. This provided seven background images such as hill shading, slope gradient and hypsometric shading.
