Acadian Seaplants Limited (ASL) is a globally recognized industry leader in the processing of seaweed-based products for food, biochemical, agricultural and agri-chemical markets worldwide and in the cultivation and processing of unique seaweeds for global food markets. The seaweed Ascophyllum nodosum (Rockweed) is the main raw material for the products produced. The end products are sold in more than 70 countries worldwide creating close to 600 jobs (full-time and seasonal) in the Maritime Provinces and contributing more than $40 M to the local economy. ASL's rockweed leases in Nova Scotia and New Brunswick along with harvested areas in Maine cover more than 3,000 km of shoreline that need to be surveyed on an annual basis to obtain the necessary information for proper resource management plan. ASL currently spends a significant amount of time and money conducting field surveys, and are interested in researching if analyzing satellite images can reduce this cost. ASL are also interested in expanding the amount of rockweed that they harvest and would like to use satellite data to assist with mapping the distribution of the resource to determine potential new harvest sites. The Applied Geomatics Research Group (AGRG) at the Nova Scotia Community College (NSCC) will collaborate with ASL to investigate the utilization of imagery from the latest high-resolution satellite, Worldview-2, acquired at low tide conditions at sites within the Gulf of Maine. Digital image processing techniques will be employed, including pattern matching and object orientated classification methods to map the Rockweed.

Dalladian Seaplants Limited（ASL）是全球公认的行业领导者，为全球食品，生物化学，农业和农业化学市场加工海藻产品，并为全球食品市场种植和加工独特的海藻。海藻Ascophyllum nodosum（Rockweed）是生产产品的主要原料。最终产品销往全球70多个国家，在沿海省份创造了近600个工作岗位（全职和季节性），为当地经济贡献了4000多万美元。ASL在新斯科舍省和新玩法沿着与缅因州收获区的岩藻租赁覆盖了3,000多公里的海岸线，需要每年进行调查，以获得适当的资源管理计划所需的信息。ASL目前花费大量的时间和金钱进行实地调查，并有兴趣研究分析卫星图像是否可以降低这一成本。ASL还对扩大他们收获的岩藻数量感兴趣，并希望利用卫星数据协助绘制资源分布图，以确定潜在的新收获地点。新斯科舍省社区学院的应用地理信息学研究小组将与美国空间研究所合作，调查最新高分辨率卫星Worldview-2在低潮条件下在缅因州海湾内各地点获得的图像的利用情况。将采用数字图像处理技术，包括模式匹配和面向对象的分类方法来绘制岩藻。
