はじめに

はじめての調査

このページでは、アプリを開き、作業するエリアをダウンロードし、記録プロトコルを選び、野外で観察記録を入力し、収集した内容を確認し、データを取り出すという、インストールからエクスポートまでの一連の流れを解説します。各手順は、詳細を記載した専用ページにリンクしています。

アプリを初めて開く

When you open EarthCape for the first time, no sign-up is required. The app creates a project for you automatically, named after your device, selects it, and assigns the Casual / incidental protocol. The project is empty — it contains no sample data, no demonstration observations, and no pre-loaded species lists. Use it as it is, or rename it before you begin.

The home screen carries the Record button, quick actions for a new observation or locality (camera, gallery or blank form), and the weather card. Everything else — the map, your data lists, protocols, projects and Admin — is reached from the Menu button at the bottom left.

1. アプリを開きます。自動作成されたプロジェクトが選択された状態でホーム画面が読み込まれます。
2. If you want to rename it, open Menu → Projects, tap the project and edit its name.
3. Take note of the protocol shown — it is Casual / incidental by default. You can change it before you start recording; see Setting the protocol below.

地図エリアのダウンロード

ベースマップは、自社インフラから配信するベクタータイルによって惑星全体を覆っています。API キーも利用上限もありません。フィールドに出る前に作業するエリアをダウンロードしておけば、通信を切っても地図、地形、3D の起伏がすべて機能します。詳しくはマップとタイルサーバーとオフラインマップをご覧ください。

リージョンをダウンロードする

1. Open the map (Menu → Map).
2. 調査地まで移動し、必要なエリアをビューポートに収めます。
3. Tap Tools in the toolbar at the bottom of the map screen, then tap Offline.
4. The panel shows "Download current view". A region name is suggested automatically while you are online — for example, "Bostanlik district, Tashkent Region, Uzbekistan"; otherwise type one.
5. Check the coordinates and size estimate. The estimate depends on the area and terrain — the district-sized example in the screenshot is about 11 MB at z6–14 — and includes the map and the 3D terrain model.
6. 「このエリアをダウンロード」をタップし、接続のある場所を離れる前にダウンロードが終わるまで待ちます。

世界の概観を追加する

The world overview (z0–5, approximately 80 MB) gives you a rendered basemap at all zoom levels, so the map is never blank when you zoom out beyond your downloaded region. It only needs downloading once.

1. In the same Offline panel, scroll down to World map. The detail line reads "Detail: z0–5 · ~80 MB"; the slider lets you change the depth (z0–7).
2. 「世界地図をダウンロード」をタップします。

プロトコルとフォームを設定する

A survey protocol defines the structure of a recording session: what a visit is, which fields appear on the observation form, and how the data is organised for export. Every observation in a project is recorded under the project's active protocol. Seven protocols ship with the app, including Casual / incidental, which is assigned automatically to new projects. You can change the protocol, clone a built-in one to edit it, or write a new one in the Protocols Studio — all on the device.

The Form builder lets you control the field layout for each entity type: show or hide fields, reorder them, group them under headings, and add custom fields. Custom fields defined before the season starts travel with the project, so the whole team's form looks the same from the first day.

1. Open Menu → Protocols. The list shows all seven built-in protocols and any you have created.
2. Tap a protocol to view it. To assign it, open Menu → Projects, tap your project and under Survey protocol tap Assign a protocol (or Change).
3. To add a custom field, open the protocol in Protocols, switch to the Form builder tab, choose the Entity type (for example Observation) and tap Add custom field. Set the caption, key, data type and section, and whether the field is Required and Show in list.
4. To share the configuration with colleagues, open the project under Menu → Projects and tap Share; the app writes a .ecsurvey setup file with the project, protocol, forms, custom fields, sites and vocabulary. Colleagues open the file on their device, or use Import under Menu → Projects. To move the records as well, export a Frictionless Data Package from Menu → Admin → File Import & Export.

フィールドでの記録

Recording a session means starting a GPS track, which creates a visit for the session, and entering observations as you work through the site. The Recording observations page covers all of this in detail.

1. Open Record from the home screen or the Record tile in the Menu.
2. Check the GPS status fields before you start: Latitude, Longitude, Accuracy, V-Accuracy, Altitude, Speed, Bearing, Satellites and Timestamp are all shown. Wait until Accuracy reaches an acceptable value for your work — ±5 m or better is typical in open terrain.
3. 画面には「記録先のプロジェクト」が有効なプロジェクト名とともに表示されます。正しいことを確認してください。
4. Tap Start recording. A visit is created for the session automatically, and observations you add while recording are linked to it.
5. 調査地を移動しながら観察を追加します。観察ごとにプロトコルのフォームが開きます。分類群とプロトコルの各フィールドを入力し、必要に応じて写真を添付します。
6. When the session is finished, tap Stop & save. The track and all observations are saved to the on-device database.

収集した内容を確認する

The data lists give you access to every record in the project as a filterable list. After a day in the field, use them to check completeness, find entry errors and open records for correction.

1. Open Menu → Observations (or Visits, Localities, Taxa, or Files depending on what you want to review).
2. The list opens with the default column set. Tap the columns icon (Choose columns) to add, remove or reorder columns — for example, add Accuracy or Altitude to check GPS quality.
3. Type in the Filter… box to narrow the list; it matches text in any shown column. In the wide (tablet) grid each column has its own filter cell, and tapping a column header sorts by it.
4. 任意の行をタップすると、レコード全体が開いて編集できます。

データを取り出す

EarthCape exports to twelve formats. The right choice depends on your destination: Darwin Core Archive for a biodiversity repository, GeoPackage for a GIS, Excel for spreadsheet work. If several people are collecting data on the same survey, Google Drive lets you push each person's contribution to a shared folder and merge them — without an EarthCape account or a server (a Google account is needed for Drive). See Export formats and Google Drive collaboration for the full procedure.

1. Open Menu → Admin → File Import & Export.
2. 取り出し先に合った形式を選びます。12 の形式がエクスポート画面に一覧表示されます。
3. Tap the format to generate the file. The filename is set automatically from the project name, its id and a timestamp.
4. Android の共有シート (Quick Share、Drive、メッセージ、Bluetooth、Gmail、その他インストール済みの送信先) からファイルを共有するか、設定済みのクラウドの保存先に直接送信します。
5. Alternatively, open Menu → Admin → Integrations and tap Export to Google Drive to push the current project — setup, your contributions, photos and an analysis-ready merge — to a shared Drive folder.
