NetMap applications include fish habitat mapping, floodplain delineation, road analyses, slope stability, riparian management and wildfire. NetMap also provides support in the form of (1) online technical help, (2) step-wise guides, (3) online mapping tools and a (4) community based approach to tool development and dissemination. Our goal at TerrainWorks is to make user-friendly GIS virtual watersheds and smart river networks available to agencies, NGOs, universities and the private sector. NetMap was created to provide off-the-shelf analysis capabilities in resource management, risk mitigation and conservation unavailable in other formats. TerrainWorks, with its flagship analysis technology “NetMap”, is being used by NOAA, US Forest Service, EPA, BLM, US Fish and Wildfire Service, Conservation NGOs, watershed councils, tribes, private sector, universities and internationally. NetMap can be built and applied anywhere in the world (Global Opportunity). TerrainWorks provides comprehensive analyses, ranging in scale from entire landscapes to watersheds to individual stream reaches, and is designed to be collaborative and accessible. NetMap’s unique set of virtual watersheds, analysis tools and online technical help, is designed to provide decision support in forestry, fisheries, restoration, riparian management, conservation, pre- and post-wildfire planning and climate change. It enables users to extrapolate survey results to unsurveyed streams by using GIS to estimate habitat abundance, potential fish abundance, or fish carrying capacity, for example. The output is a shapefile of survey reaches with both the survey data and attributes associated with the digitally produced stream layer (e.g., drainage area, gradient, and valley width). It hosts a climate change component that includes projected changes in seasonal hydrographs, changes in the likely location of snow-to-rain transition zones, and thermal loading. This tool based on a geographic information system matches stream-survey data to digitally produced stream layers created with NetStream software.NetMap contains models that allow the user to conduct analyses on various parameters that influence aquatic ecosystems such as wood recruitment, erosion sources, and potential habitat. That’s all folks.A GIS-based tool for linking field and digital stream data. Okay now, let’s create some init scripts so both `lb` and `bro` start at boot time. You should now see some logs start to roll in.Ħ. Make sure to create the same amount of pipes (`-p`) as `lb_procs` from the Bro config. Now, lets start `lb` in the background and fire up Bro. There’s currently no port for `lb` and you won’t find it with other netmap utilities shipped under `/usr/src/tools/tools/netmap`. This is all well and good, however packets won’t be balanced across your four `lb_procs` without the help of a utility called `lb`. If the interface you’re having Bro monitor is dedicated to Bro and nothing else, enable `promisc` on the interface. Here, we’re instructing bro to create 4 load balancer processes for monitoring the the igb1 interface. Now, we just need to configure bro to use netmap. Now we can compile and install the netmap plugin.Ĥ. Otherwise, proceed with the typical configure, make, and make install.ģ. Instead, after performing the build, just grab `./build/dist/Bro_Netmap-0.1.tar.gz` and copy/extract it where you need (with similiar FreeBSD version). Note, if you just need the plugin (for another system with a binary install using pkg), don’t run `make install`. Download the source tarball and extract it. Pkg install -y bash git flex bison cmake libpcap python py27-sqlite3 caf swig30`Ģ. First, we’ll need to install the necessary dependencies for compiling bro. Not to worry, we’ll just install Bro from source. Furthermore, the port doesn’t support building any auxiliary plugins. However, as of FreeBSD 11.1 (bro-2.5.1) the binary package doesn’t ship with the needed netmap plugin. Here, we’ll show how to set Bro up to use it.īro provides support for monitoring interfaces using netmap. NETMAP is a framework for very fast packet I/O from userspace with support for FreeBSD, Linux, and even Windows.
