GPSロガーにGARMIN OREGON 300を使っています．大分前に販売は終了していて，バッテリーボックスや外装がへたっていますが未だ使えています．単3電池2本で12〜16時間程は動作するしいざとなったらUSB経由でも動作します．防水(手持ちのは外装が破損してもう防水ではない)で雨の中も普通に使えるし，地図にOpenStreetMapのデータを使うことも出来ます．
これを主に自転車のハンドルにマウントして使っています．
知らない道路を走るときなどはトラックログを前もって作成しておいて参照しながら走ると迷わず時間もロスせず走れていい感じです．(ブルベなどに最適)
ルートの作成にはJOSMやルートラボを利用しています．
走行後はログからデジタルカメラの写真にジオタグを埋め込んだりログや写真を見ながらOpenStreetMapに情報を入力したりしています．
- OpenStreetMap
- GPS で色々遊ぶ – Speaker Deck(GeoTag埋め込み方法)
そんな感じで便利に使っていたのですが，初日の出を見に行ったときのポタリングのデータを見たらデータがおかしいです．電源を入れ直すたびにその場所の標高が-になっているとかもおかしいのですが，日付が1999年05月17〜18日になっています．実際は2019年01月01日です．
GPSの1999年8月21日問題?と思いましたが，次は4月なので多分違う．
もしかしてOREGON 300は2019年のデータを扱えない?
データはこんな感じで年月日と標高はおかしいですが，位置情報と時分秒は正しそうです．

標高はとりあえず置いておいてsedで年月日差し替えでとりあえず写真にジオタグを付けたりするのに使えました．

しかしアップデートにはWindows端末が必要で今まともな実機がないので面倒……．
仮想環境のWindows 10 Pro 64bitを使ってアップデートできました．
ちなみに今 $11.80 でWindows 10 Pro OEM ライセンスがセールしてたりするので環境がない人はこれを買って仮想環境に入れとくと今回みたいなときに便利です．
そして庭に出て測位してログを確認したら正しい日付のログが録れていました :)
しかし大分古いので新しいQZSS対応あたりの世代のOREGONとか欲しいですね．
OREGON だと600以降かな?カメラはいらないので600/600t/700?
