geowebcache проблема с отображением слоем

Добавлено: 22 дек 2010, 21:36
Djinn18
не могу настроить кэширование, наверное из-за такой проблемы
400: Requested horizontal resolution: 0.0042968750000000056 , best match: 0.0054931640625 exceeds 10% threshold. Perhaps the client is configured with an incorrect set of scales (resolutions), or the DPI setting is off compared to the one in GWC ?
на демо отображается http://localhost:8080/geowebcache/demo/ ... =image/png

это ссылка на рабочий кусочек который скапирован с демо
а это с вебстранице где должен отображаться этот кусочек
я не могу понять, почему не отображается

Кэш создается под конкретное кол-во зумов. У вас и в кэше не совпадают значения масштабов (увеличений).
Про это он и говорит - нестыковка больше 10%. Нужно в параметрах карты (map) заполнить массив resolutions. Поищите готовый в примерах demo. Или сами посчитайте (путанное занятие).

Вот почему все берут GWC? Есть же GeoJazzy - простой, без этой мороки с resolutions. Для новичков самое то.

Если будет время, то завтра ваш код посмотрю внимательнее.

Про GWC статья немного устарела, да и описание там минимальное. GeoJazzy тоже есть в статьях. Он очень простой, продвинутых фич в нем не хватает, но для первого знакомства - рекомендую.

где-то я явно что-то не то прописал

если самому просчитать, как тут resolution = scale / 39.3701 / 72
['m'] = 39.3701
но у меня 'km', это сколько?
и dpi, всегда 72?
а почему в другой теме писалось( /256)

Слой 'borders' у вас хорошо работает? Судя по ошибкам это проблемы UMN MapServer, а не GWC.

Написать второй GridSet. Посмотрите в оригинальном файле из дистрибутива, там были сетки и слои на разные СК.

В оригинале, насколько я помню, были две сетки - на epsg:4326 и 900913.
Судя по логу вы продублировали gridSets, а не gridSet.
