ArcGIS Maps SDK for JavaScriptに軽量なHTML5 / HLSビデオストリーミングレイヤーを統合するためのベストプラクティスは？
Esri開発者コミュニティの皆さん、 現在、リアルタイムの地理空間データフィードとカスタムメディアロケーション用の動的なHLSビデオプレイヤーオーバーレイを表示するモダンなウェブベースのマッピングアプリケーションに取り組んでいます。 ArcGIS Maps SDK for JavaScriptによるコアの空間レンダリングは問題なく動作していますが、クライアント側のパフォーマンス最適化、特にユーザーが地図上の異なる空間ビデオマーカーを頻繁に切り替える際のメモリクリーンアップとGLバッファ割り当ての保持回避に注力しています。 WebGISアプリケーションに動的なウェブメディア /…

カスタムWebマッピングアプリでの非同期データ読み込みの取り扱いとクライアント側レンダリング負荷軽減のベストプラクティス
Esri Developer Communityの皆さん、 現在、クライアント側スクリプトが非同期データ読み込みや重いフィーチャレイヤーのレンダリングをどのように処理するかに焦点を当てたカスタムWebマッピングアプリケーション開発のワークフローに取り組んでいます。 頻繁なAPIリクエストや大規模な空間データセットを動的にWebアプリにストリーミングする際、メインスレッドの応答性を保ち、高頻度のズームやパン操作中のUIのカクつきを避けることは一般的な開発課題です。 *…

カスタムデータフィードでGIS機能をどのように使えますか？
カスタムデータフィードを開発していて、ある座標系から別の座標系に値を投影する必要があります。 そのようなメソッドはデフォルトで利用できると思ったのですが、何も見つかりません。 すでにGISプラットフォーム上にいるのに、別のライブラリ（例えばproj4）を含めるのは過剰な気がしますよね？

ページネーション付きカスタムデータフィード
私は、サードパーティのWeb APIを使用してデータを取得するカスタムデータフィードを開発しています。このWeb APIはページネーションに対応しているため、ArcGISのresultOffsetとresultRecordCountパラメーターを使ってサードパーティから取得するレコード数を制限できます。 しかし、CDFフレームワークは私が返すフィーチャに対してresultOffsetを再度適用しているようです。再び、例えばリクエストにresultOffset=10&resultRecordCount=10が含まれている場合、データフィードは実質的に0件のレコードを返します。 結果では、すでにfiltersApplied =…

PostgreSQLジオデータベースの「gdb_geomattr_data」列の曲線情報が属性編集時に失われる
他にPostgreSQLの従来のバージョン管理編集でこれに遭遇した人はいますか？ ArcGIS Pro 3.4および3.7の従来のバージョン管理で属性を編集すると、曲線ジオメトリが失われます。st_geometryの代わりにPostGIS拡張機能を使用したSDE対応のPostgreSQLデータベースを使用しています。 バージョンでシェイプが最初に作成されると、頂点を表示すると真の曲線があることがわかります。また、追加デルタテーブルの「gdb_geomattr_data」列にも値があります： select encode(gdb_geomattr_data, 'hex') from dor.a264 where objectid =…

SCF (ZIP3) KML File?
Newbie to this. I'm interested in mapping activity by the SCF areas (this is the first three characters of the U.S. ZIP). I am using (Mirco)Strategy, as it has ESRI maps built into it, but I think I need a custom kml file that would define the areas? Example: SCF of 727 is all of the ZIP's between 72701 and 72799. I want…
