When suppressing duplicate cafes and place names, look back a certain distance along the route rather than just the previous point of interest. When searching for cafes, use SearchIntersect() to return all entries in the bounding rectangle, not just the nearest. Remove (most) hard-coded constants and allow these to be overriden by options to the NewGPXSummarizer() constructor. |

GPX Utils
Utilities for analyzing and indexing GPX routes.
Compiling placenames.bin
This step extracts bounding boxes for populated places from the OS Open Names dataset, which is available for free download: https://www.ordnancesurvey.co.uk/business-government/products/open-map-names
go run ./cmd/save-gob/... opname_csv_gb.zip ./pkg/placenames/placenames.bin
I have included a compiled extract in this repository so you can skip this step.
Binary embedding
We use mule to embed the gob data in the compiled binaries:
go get github.com/wlbr/mule
Make sure the mule command is on your PATH before running go generate.
Compiling
mkdir -p bin
go generate ./...
go build -o bin ./...
Usage
analyze-gpx
To analyze a single GPX track:
./bin/analyze-gpx FILENAME
This will write a JSON summary to STDOUT.
To analyze an entire directory:
./bin/analyze-gpx DIRNAME
This will scan the directory and, for each file with suffix .gpx, will output the analysis to a corresponding file with suffix .json.
serve-rwgps
This will start a small server to analyze RideWithGPS tracks.
./bin/serve-rwgps
It defaults to listening on port 8000, override by setting the LISTEN_ADDR environment variable:
LISTEN_ADDR=127.0.0.1:3000 ./bin/serve-rwgps
Then to query a route:
curl http://localhost:3000/rwgps?routeId=30165378
To include CTC Cambridge refreshment stops in the output:
curl 'http://localhost:8000/rwgps?routeId=29766778&stops=ctccambridge'
See https://ctccambridge.org.uk/waypoints for information about this data source.
For stops farther afield, you can try the stops maintained by https://cafes.cyclingmaps.net/
curl 'http://localhost:8000/rwgps?routeId=29766778&stops=cyclingmaps'
