Use Export to Avenza Maps to generate map packages that can be directly uploaded to the Avenza Map Store, an in-app map store for the Avenza Maps app on iOS, Android, and Windows Phone. You can also generate map packages and load them on your own devices through iTunes File Sharing or the Android file system, Dropbox, or specify a URL to your own location. When maps are uploaded using the Upload to Avenza Maps feature, it is put into the Prepare for Review state on the Avenza Map Store.
All maps submitted to the Avenza Map Store are reviewed to ensure they are referenced accurately, perform as expected, and contain appropriate content. As you plan and create your maps, be sure to keep our review and design guidelines in mind so that you can get through the map review stage.
Requirements
While any document with a specified coordinate system can be exported as a map package using Export to Avenza Maps, you must have a Avenza Map Store vendor account to use Upload to Avenza Maps. Visit www.avenzamaps.com for more information on how to be a Avenza Map Store vendor.
Exporting to Avenza Maps app
Getting your maps ready for the Avenza Maps app is a two part process depending on how you send or load the map package.
|
Scenario 1 |
1.Use Export to Avenza Maps to create map packages. 2.Use Upload to Avenza Maps to prepare map packages and upload for submission review.
The advantage of using Upload to Avenza Maps is the ability to easily populate details of your maps within Adobe Photoshop without having to go to the Avenza Maps vendor site. |
|
Scenario 2 |
1.Use Export to Avenza Maps to create map packages. 2.Go to the Avenza Maps Vendor website to upload and prepare map packages for submission review. |
|
Scenario 3 |
1. Use Export to Avenza Maps to create map packages. 2.Use iTunes File Sharing or the Android file system, Dropbox, or specify a URL to transfer your map packages to your device.
This scenario doesn't upload map packages to the Avenza Map Store. It only loads map packages to your mobile device. It is a good way to quickly test your maps without having to go through the review process of the Avenza Map Store. |
With an open image, go to File menu > Export > Export to Avenza Maps. Choose a folder to export map packages to and specify any of the available options.
|
Folder |
Browse to a directory that contains map packages ready for export. |
|
Convert to indexed color mode (recommended) |
Create map packages in index color mode. These map packages create a small footprint on mobile devices. Note that this will not retain the full spectrum of RGB color space. It is recommended to have this option enabled. |
|
Image resampling |
The resampling method assigns color values to any new pixels based on the color values of existing pixels. By default, the Adobe Photoshop resampling method will be used. You can change the default resampling method in Adobe Photoshop preferences. |
|
Launch upload dialog after creating files |
This will prompt the Upload to Avenza Maps dialog after export. |
|
Open export directory after processing |
Open the file browser of the specified folder after exporting is complete. |
The following are available image resampling methods:
|
Bicubic (smooth gradients) |
Takes a weighted average value of the sixteen pixels closest to the transformed location in the source image. |
|
Bilinear |
Takes a weighted average value of the four pixels closest to the transformed location in the source image. This method results in a smoother image than the nearest neighbor method but at the expense of more processing time. |
|
Nearest Neighbor (hard edge) |
Takes the value of the pixel that is closest to the transformed location in the source image. This is the fastest method in terms of processing time and is the method to use to preserve a colour panel during image transformation. It is also the best method to preserve original colours in some non-RGB colour modes, such as CMYK, by avoiding the internal conversion to/from RGB. |
|
Automatic |
Adobe Photoshop chooses the resampling method based on the document type and whether the document is scaling up or down. |
|
Preserve Details (enlargement) |
A method for enlarging images that attempts to smooth out noise. |
|
Bicubic Smoother (enlargement) |
A method for enlarging images based on Bicubic interpolation but designed to produce smoother results. |
|
Bicubic Sharper (reduction) |
A method for reducing the size of an image based on Bicubic interpolation with enhanced sharpening. This method maintains the detail in a resampled image. If Bicubic Sharper oversharpens some areas of an image, try using Bicubic. |
The Image resampling options may differ depending on your Adobe Photoshop version.
Map Package Contents
A map package contains all of the content required to allow it to work on the Avenza Maps app. When uploading a map package to the Avenza Map Store, the ZIP file must be accompanied by all four associated files. For example, if you have an exported map called MtOlympus, the ZIP would be called MtOlympus.zip and its four associated files would be called MtOlympus_preview.jpg, MtOlympus_95px.jpg, MtOlympus_233px.jpg, and MtOlympus.csv. These files must have the same name as the ZIP file and should not be renamed independently. A map package will not get uploaded if any of the associated files are missing.
When loading a map onto your device through iTunes File Sharing or the Android file system, Dropbox, or a URL, only the ZIP file is required.
When viewing a map package folder, it will look like the following:
|
Map Package Contents |
Description |
|
*.csv |
A comma separated value file with coordinates that define spatial extent. |
|
*.zip |
ZIP file contains a tiles folder containing the images required to render the map in the Avenza Maps app. The ZIP also contains a thumbnail file and reference file, both of these are required in the zip package. The zip package structure should not be altered. |
|
*_95.jpg |
Small preview image; can be customized and used on vendor site. |
|
*_233.jpg |
Large preview image; can be customized and used on vendor site. |
|
*_preview.jpg |
Main preview image; can be customized, however the image size, color mode and name should not be modified. You can create custom preview images to branding purposes. |
A map package will not get uploaded if any of the map package files are missing.
