eAtlas World Baselayer Version 1 (NERP TE 13.1, AIMS)

The eAtlas baselayer is a collection of datasets from third parties styled and combined together to produce a world wide map layer with reasonable detail across the Great Barrier Reef suitable as a baselayer in web mapping applications.

The primary basis for this baselayer is the Natural Earth 2 public domain raster map of the world. Overlaid on this is country outlines, cities and Great Barrier Reefs.

It has a focus on Australia and the Great Barrier Reef and includes a high resolution coast for Australia (100k) and an even high resolution coast for Queensland (50k).

The baselayer has three levels of nested detail. It starts with the world view datasets (Natural Earth 2 & 10m countries) combined with a high resolution Australian coastline (Coast 100k) combined with a still higher resolution Queensland coastline (GBR features). In addition to this the GBR features combined with the GBR dry reefs provides detailed outlines for reefs within the Great Barrier Reef Marine Park.

This nesting is achieved by using a layer group in GeoServer to sandwich all 6 layers together into one map. The styling of the 10m countries layer is done so that all countries except Australia are rendered, leaving a hole for the high resolution Australian coastline. The Coast100k it is styled so that all states are shown except Queensland; again to leave a hole for a higher resolution Queensland coastline. To get the Queensland coastline the GBR features mainland is used.

Format:

This dataset collection is organised as files in a structure the same as the configuration of GeoServer version 2.1 - 2.3. This allows it to be easily deployed as a web map service. The files can simply be pasted into the GeoServer directory. The data, along with the configuration and styling will be installed. This quick install procedure has been tested on version 2.1.0, 2.2.4 and 2.3 of GeoServer. More recent version may require manual editing deploy the data.

The size of this dataset is 260 MB.

Note:

This dataset has been superseded by the higher resolution Bright Earth eAtlas Basemap (NERP TE 13.1 eAtlas, AIMS) dataset.

This dataset is filed in the eAtlas enduring data repository at: data\NERP-TE\13.1_eAtlas\World_NERP-13-1_eAtlas_Basemap_v1-2013

eAtlas基础底图（eAtlas baselayer）是由第三方数据集集合经样式化处理与整合后生成的全球地图图层，在大堡礁（Great Barrier Reef）区域具备适度的细节精度，可作为网络地图应用中的基础底图使用。

该基础底图的核心基底为公共领域的全球栅格地图Natural Earth 2，在此基础上叠加了国家边界、城市与大堡礁要素。

本底图重点覆盖澳大利亚与大堡礁区域，包含澳大利亚高分辨率海岸线数据（100k）以及昆士兰州更高分辨率的海岸线数据（50k）。

该基础底图包含三级嵌套细节层级：首先以全球视角数据集（Natural Earth 2与10m国家边界数据）为基础，叠加高分辨率澳大利亚海岸线数据（Coast 100k），再叠加分辨率更高的昆士兰州海岸线数据（GBR要素）。此外，GBR要素与GBR干礁数据结合后，可为大堡礁海洋公园内的珊瑚礁提供精细的轮廓信息。

该嵌套层级通过GeoServer中的图层组实现，将全部6个图层整合为单一地图。对10m国家边界图层进行样式化设置时，仅渲染除澳大利亚以外的所有国家，从而为高分辨率澳大利亚海岸线留出空白区域；对Coast100k图层进行样式化时，仅显示除昆士兰州以外的所有州份，再次为更高分辨率的昆士兰州海岸线留出空白区域。昆士兰州海岸线则通过GBR要素陆地区域数据实现。

格式说明：
本数据集集合的文件组织结构与GeoServer 2.1至2.3版本的配置结构一致，可便捷部署为网络地图服务。仅需将文件直接粘贴至GeoServer目录即可完成部署，数据、配置与样式将同步安装。该快速安装流程已在GeoServer 2.1.0、2.2.4及2.3版本中完成测试，更新版本可能需要手动编辑以完成数据部署。

本数据集总大小为260 MB。

备注：
本数据集已被更高分辨率的Bright Earth eAtlas基础底图（NERP TE 13.1 eAtlas, AIMS）数据集所替代。
